Zanussi Washing Machine Motor Brushes

Posted on 03 February 2008 by Tony

As you well know, identifying Zanussi Washing Machine Motor Brushes is quite difficult because the manufacturer took it upon themselves to design a washing machine that was produced with different types of motor.

Electrolux, who are the people who own the brand for Zanussi amongst others used three different types of motor. These are SOLE, FHP and CESET for washing machines and washer dryers with spin speeds between 650 rpm and 1600 rpm.

Each type of motor may have been alternatively fitted to the same machines during production but are perfectly interchangeable with each other. The only thing we need to know is, we fit the correct carbon brush set to the appropriate motor. Hopefully the table below will help in identifying your correct brush set.

Cooker Hood Installing and Design

Posted on 19 November 2007 by Tony

There are a wide range of manufacturers available today that can provide you with that ideal cooker hood. Things to consider when choosing a Cooker Hood are design and installation. These are paramount in choosing the correct operation of your kitchen appliance.

One company worthy of a mention are D R Cooker Hoods. On their website they are quoted to say ‘ Elica are the world’s No 1. They are the company that manufactures for most of the recognised brand names. Elica, the brand exclusive to D R Cooker Hoods, the Company that have pioneered the product for over 25 years.’

Pretty bold statement that but go check them out for yourself. Loads of information there and stuff you never really thought you needed to know.

The one thing to remember with a cooker hood is, you need maintain the efficiency of the hood so it can give you years of uninterrupted service. To do this you need to check the filters are free and clean of grease and debris.

Grease Filter

Your hood may be of the recirculating type or evacuation type so will be fitted with different types of grease filters but mainly they will absorb grease and dust particles and the most commonly used grease filters are those made from metal, disposable paper or active carbon.

Metal grease filters are typically long-life filters and consist of layers or lattice like. The deeper the layers can have an effect on the extraction process and so lessen the efficiency of the cooker hood. For this reason it is important that the correct type of grease filter be fitted.

Dishwasher wont continue the cycle

Posted on 10 November 2007 by Tony

Your dishwasher, when correctly installed, can give you years of uninterrupted hassle free washing and cleaning. Then one day you go to switch on your trusty dishwasher and nothing happens.

What’s the first thing you going to do to fix this annoyance. Well I guess you might find the answer right here on the appliance repair help site but don’t reach for the phone book just yet because this might be something you can fix your self.

I’ll explain. Modern day dishwashers like those manufactured by Bosch and you can include Siemens and Neff in that have a built in safety feature protecting the dishwasher against flooding. The technical term is ‘Anti Flood Device’. There are other manufacturers who provide the same features but for now I’m only going to talk about the Bosch type machines.

In the base of the dishwasher in the plinth there is a float switch. This is your ‘Anti Flood Device’. In the event of your dishwasher over filling, the plinth fills with water, the float rises and actuates the switch. On a Bosch dishwasher this switch will do two things.

Firstly, it will send a signal to the programmer device to notify there is a fault and output a message in the form of a code to some sort of display.

Secondly, the pressure switch acts as the water level indicator for the sump of the dishwasher so when the water level rises the pressure switch will activate the drain pump.

So before you consider throwing good money at new dishwasher, try doing a bit of fault finding your self and you might save yourself a ton of money.

Just a quick update to this ‘Dishwasher will not continue the cycle’ article. There appears to be a common thread in the comments below. Most faults can be referred to the fact that the Anti Flood Overflow device has activated. I have included an image here to show what the anti flood may look like in a Hotpoint DWF40.

Anti Flood Device

You can see it here as items 17 18 and 19 collectively.

Let’s assume your dishwasher has over filled at some stage and with time the water in the drip tray has now evaporated, the float item 19 can have a tendency to stick and make the switch item 18 stay in an actuated state. This can give a false positive. Try to reset the float switch or check even that there is no water in this drip tray. When the float is activated it can cause the drain pump to be permanantly in a drain mode

How to fit a Bearing in a Washing Machine

Posted on 19 September 2007 by Tony

OK We all have a washing machine in our homes. Well nearly all of us, but at some point in our lives and not the washing machines, we may have to attempt to replace the bearings in our washing machine.

As an engineer I often get asked ‘How do I fit a Bearing in a Washing Machine?‘ by friends and family. So I figured and should show all you guys how I do it by writing this small article right here.

First things first. You have got to pick a good day on which you are going to attempt this. If you are new to this, you will have to give your self approximately 8 hours. In real time this is 2 days of anyones time. Hotpoint engineers can do this job in about 2 hours or so but this is not a race as we only want to do this the once.

I’m assuming you already have a decent tool kit otherwise you wouldn’t be attempting this washing machine bearing change. A decent screwdriver set, a few open ended spanners - 10mm, 13mm, 17mm, 19mm - and a decent hammer, a big one, no lets make that a really big one. As an apprentice engineer, brute force and ignorance was my biggest asset and it still carries to this day so don’t be afraid to use a big hammer.

We mentioned time didn’t we. We need to pick a day of the week and since most peoples free time is a weekend, lets pick a Saturday. That’s best because I work a Saturday and if you get stuck you can always give me a ring. The next thing to do is research the type of bearings you will need, so establish what the model number of your washing machine is by identifying the rating plate. Its on the inside of the door.

Once we know this either send me an email and I will identify the bearings for you or look them up in our spare parts catalog. Either way we need to know we can get the bearings and the drum seal before we attempt the repair.

Below I have included a drawing of a typical washing machine drum. This will help you identify the parts and aid your attempt and dismantling the washing machine.

Refrigerator Water Filters

Posted on 16 August 2007 by Tony

The Refrigerator water filter is one way of ensuring that the water you drink from your refrigerator dispenser or even the ice cubes you use are pure. What I mean by that is the water you use from the refrigerator has been cleaned of the heavy deposits and odours.

Refrigerator water filters are designed for use in refrigerators with ice-makers or dispensing water through the door. These water filters systems are fitted by way of a water line that runs from your plumbing or mains supply to your refrigerator where the water is then filtered and cooled, the refrigerated water you have filtered is usually used mainly for drinking water only.

Water filters for Refrigerators are normally located either inside the fridge or at the bottom of the unit inside the grill, or even at the top of the refrigerator. The in-line Refrigerator water filter is designed for use on refrigerators with icemaker and/or water dispensers and is a small activated charcoal filter designed to filter out certain solids and chemicals from your water source before the water gets to your water dispenser or ice maker. Carbon is the main substance utilized in water filtration processes as it has the potential of absorbing a lot of the contaminants found in water.

Although many refrigerators are designed with a built-in water filter, any refrigerator that has an ice-maker or water dispenser on the door can be outfitted with a water filter. In additions to refrigerators, this type of water filter can be used in conjunction with water fountains, ice machines, commercial coffee makers or water coolers. Built-in refrigerator water filters are becoming increasingly popular, and most of the major makers of refrigerators, such as Frigidaire, GE, Whirlpool, Kenmore, Sears, Samsung, and LG, offer these types.

Using a water filter is one way of ensuring that the water you drink from your refrigerator dispenser or even the ice cubes you use are pure. The water filters guarantee safe clean great tasting drinking water and ice making. Many makes of modern refrigerators have built-in filtering systems that help make crystal clear ice and water from door dispensers. Refrigerator water filters are made to mount on a plumbed refrigerator and provide filtration for drinking water and ice from your refrigerator.

How to remove an Oven door

Posted on 26 March 2007 by Tony

We get this asked all the time. How do I remove the oven door?

It’s actually quite difficult to explain this over the phone and I get asked this virtually on a daily basis. I mean, how do you explain what an hoofadoofa is and what the roundy bit on the twisty mode is. People naturally have their on interpretation of the names of the different parts are so it can get confusing, so lets have a picture.

Typical Oven Door Hinge

This is only an example of what a hinge might look like, this one is from a Hotpoint Cooker and yours might look completely different but the principle is the same.

Firstly open door fully and then place the metal clips, part B, which form part of the hinge arm, part A, onto the hook on the under side of the hinge arm, part C. Once you have done this you have then locked the hinges in position but be aware that the hinge springs are now fully loaded.

Now you can remove the door as illustrated in the second picture here. There are two movements here but you must hold the door by the sides. Do not hold the door by the handle because once the door is off the oven you will have the weight of the door on the handle, it will break off and your door will be in a thousand bits on the kitchen floor. I have no problem in supplying you with a new door but you don’t want to part with 100 quid at this stage.

While holding the door at the sides, lift it to 45 deg and then pull it towards you. You should now be able to safely remove the oven door.

Noisey Washing Machine Bearings

Posted on 05 March 2007 by Tony

The washing machine is very noisy.

Although difficult to describe, the noise you hear is probably down to worn bearings. The bearings will fail mainly due to the fact that the bearing seal has failed, water will then pass to the bearings and start to break down the lubricant.
With the back off your machine, remove the drive belt from the main motor and drum pulley. Spin the drum by hand. Is it lumpy and noisey. Have you any lateral movement of the drum when you try to lift it from the front of the drum.
Other things to consider is run up the motor while the belt is removed.

 

Does the drum turn or spin.

A washing machine has a motor that turns the drum. Depending on what make of model you have, it will be fitted with either a commutator motor (one that has carbon brushes) or an induction motor (a brushless motor).
On first inspection you may not be able to identify what motor you have. If you have never seen a carbon brush it might be worth checking out the pictures we have available listed under the relavent machine section or see sample motor carbon brushes.
If you suspect the motor failure, first check to see if you have a brush type motor. If so carefully remove the brush from the motor. Lots of carbon dust in and around the brushes may indicate excessive wear. Check the length of the carbon within the carbon brush holder. Anything less that 10mm then change them.
