How to find your fault on your washing machine.

This short guide is designed to outline the most common problems on a washing machine, although many people that read this tutorial are looking for a quick way to find out how to repair a washing machine there are not really any shortcuts. What this guide is intended to do is compliment all the other information that you will find in the site detailing individual washing machine tutorials on how to repair the faults as well as the other articles in this section to allow you to correctly diagnose the problem or, at least have a clue about what the fault is and how to go about repairing your washing machine. You will always be able to ask questions in the blog for people to answer or us.

Safety First,

When accessing the washing machine, make sure you disconnect the washing machine from the electric supply

Specific Washing Machine fault to see causes and solutions

  • Appliance is leaking
  • Appliance will not start
  • Clothes are damaged after washing
  • Clothes are still dirty
  • Door will not open at end of programme
  • Drum will not rotate
  • Machine overfills and floods
  • No water entering machine
  • Stuck on wash cycle
  • Washer doesn’t fill with water
  • Washer/Dryer doesn’t dry

Common Washing Machine Problems.

Please bear in mind that this washing machine and washer dryer guide is very generic and offers only rough guidance and not our expert opinion on any one appliance or brand they are all slightly different, so some common sense will be required.

Washing machine will not start, no power.

There are lots of things that can cause this to happen but as with any fault diagnosis, start at the beginning and work through the problem methodically. So begin at the plug and make sure that there is power to the socket and that the fuse is okay before looking any further.

  • Mains filter
  • Door lock
  • Mains cable & terminal block
  • Main power switch
  • Control module or PCB

Washing machine noisy.

Objects trapped in between the outer tub and drum can also be the cause of noise, things like bra wires are extremely common to be retrieved from around the heater between the drum and they can cause damage to the machine and any clothing in it. If you can, remove the wires before washing or wash them in a special wash bag.
When machines are a few years old then it is very possible that the bearings are either faulty, or starting to collapse. With bearings the sooner that they are replaced the better as there is liable to do less damage, not using or minimising the use will help to avoid further damage.
Replace them as soon as you can see videos on how to change bearings.
Suspension stability can also cause excessive noise; obviously a fault with the suspension system can also produce a lot of noise from the machine shaking badly.

  • Noisy pump
  • Object in the drain pump
  • Object trapped in the tub
  • Bearings faulty
  • Washing machine not levelled correctly
  • Faulty dampers or suspension
  • Poor flooring or installation

Washing machine will not drain or is noisy on drain.

Generally this will be some sort of drain pump failure or blockage, see video for more help on this.

  • Drain pump blocked
  • Drain pump faulty
  • Waste outlet hose blocked
  • Sump hose blocked
  • Object in pump (coin, screw, baby sock ETC)
  • Poor flooring or installation

Washing machines drum not washing, turning or spinning.

Normally when this happens people often assume that the belt is faulty and, whilst this can be one of the causes it likely,
The most common fault still is if they have fitted the carbon brushes to the motor. See videos on this topic.
It can also be a problem with the speed control PCB or module or even what is referred to as the “tacho generator” on the washing machine’s motor.
Assuming everything else works these should be checked:

  • Belt
  • Faulty carbon brushes
  • Speed control PCB or module
  • Motor capacitor (where fitted)
  • Main control module
  • Motor faulty

Washing machine not heating or over heating.

Pretty easy one usually, in most cases there will be a faulty heater, thermostat, thermistor or pressure switch but there can be other causes. See videos on this topic.

  • Heater
  • Thermostat
  • Thermistor
  • Pressure switch/level sensor
  • Timer or control PCB/module

Washing machine not spinning.

(Also see previous ‘Washing machines drum not washing, turning or spinning.’)
Remember if the machine cannot drain within its time frame correctly then the spin will often abort so bear this in mind when looking for a problem.

  • Faulty or worn carbon brushes
  • Blocked pump or drain
  • Speed control PCB/module
  • Faulty contacts on fast cam within the timer
  • Faulty capacitor (where fitted)
  • Faulty motor
  • Faulty motor tacho
  • Overloaded or out of balance, can be made worse by poor installation or flooring
  • Faulty pressure switch

Washing machine not filling.

First, check the water supply is okay! Taps can stop working or you end up with very low water pressure.
Check the water valves or solenoids
Pressure switch is connected to the pressure chamber by a small bore air hose these can become faulty or the air passage can block.

  • Water supply
  • Water fill valve
  • Pressure switch
  • Control PCB/module
  • Bad smell from washing machine
  • door seal mouldy
  • Mould problems on seals and hoses.
  • dirty soap drawers.
  • Waste hose or trap problem

Washing machine lights flash and won’t work

This is most likely a new electronically controlled machine and the flashing lights will almost certainly be giving you a fault code

  • See manual to find code fault

Washing machine leaks from the front (see video tutorial on this)

  • Soap Drawer
  • Soap Drawer box to tub hose
  • Door Seal
  • Door glass
  • Washing machine leaking from underneath (see video tutorial on this)
  • Drain pump leaking
  • Filter is leaking
  • Tub gasket leaking on drum
  • Hose leaking (any of them)
  • Water pressure too high
  • Heater gasket perished
  • Door seal gasket
  • Pressure switch or sensor fault (overfilling)
  • Physical tub damage
  • Soap drawer damage

    I have a Hoover VT D2 washing machine which gave off a burning smell. There is a sooty deposit round the drum at the rear of the machine. Is this likely to be a burnt out bearing?
    Any advice gratefully received.

    Hi
    My Beko washing machine has just suddenly stopped mid wash. I’ve managed to drain the water and remove the items.

    The lights all work on the programmes but when I press the start button it just goes back to pause mode. You can hear it click as if it will start the programme but it doesn’t

    Any ideas?

    Great site, very useful. I changed the brushes you sent me quite easily, thanks.
    Site could be improved if the bullet points above in identify the fault linked to the respective video.
    I still have a fault, possibly PCB. The drum seems very loose and when loaded bangs in the side. When empty, on the spin cycle, it will go once, then cut out (the momentum keeps it turning for a bit). It will then try again a minute or two later ( not timed).
    What’s wrong?

    Hi hope someone can point me in the right direction? I have a Bosch washer/dryer model WVG30461GB. So you select the program you require and then press go, at that point you hear the door lock click shut and the door lock logo lights up on screen and then starts it’s cycle. Now when I press go you can hear the lock locking and unlocking 3 or 4 times and the lock logo will not stay lit so therefore will not cycle. Occasionally with frantic pushing of the button it will cycle but very hit and miss. I’ve fitted a new door lock same problem! I fitted a new pcb board still no good! I’m out of ideas. Can anyone help?

    My indesit washer has started to go no further than the rinse/spin cycle, once ts spun, it repeats the rinse/spin cycle, what could this be ?

    I have a Siemens 1600XL washing machine. Yesterday I put the machine on rinse and the drum was just rocking backwards and forwards and the water would not drain. As per the instruction booklet, we drained the water using the drainage hose and cleaned the pump. I put the machine on again, programmed it and pressed start to begin a wash cycle. The indicator light came on and the clock is counting down but now the machine is not moving at all so the cycle has not even begun. The door is firmly closed so now I do not know what other steps I can take. Could you please advise.
    (reference on side of machine is WXL T166 AGB H 164 364 1600 min)

    We have an excellent Zanussi 1000 washing machine which has given faultless service over 31 years but we now find that the drum will not turn. It is not ‘stuck’ but for some reason the motor does not turn it. Bushes? Belt? Electrical connection? Any ideas please!

    I have a zanussi Aqua cycle 1000 washing machine it has developed a habit of the timer sticking just before it completes the washing near the letter G…………………… I HAVE FOUND BY JUSY GENTLY KNOCKING THE SWITCH it then completes the washing without further problems……………….any suggestions ?

    Typical Kenmore top load washer about 15 years old. It is not the timer, replaced that and no difference. Over rode lid switch. Here’s the deal: after pumping out wash water, will not automatically go into spin. BUT, if you push in and pull out timer knob, it will start to spin! With no rotation of the knob, just push/pull.????

    Bosch wishing machine was showing E18 error code.
    Drained the machine, cleared the filter and checked the white “fan” span freely which it did.
    Out machine on again but still issue. So took the machine out and found the soil pipe was thick with gunk, so put the machine into 90degree was with vinegar to clear but still the machine won’t drain properly…. and get stuck at end of cycle with lots of soap suds and drum with water. Any ideas?

    My Beko washer does not wash the liquid conditioner out of the drawer.
    Water washes the powder section, but the conditioner stays in the drawer.
    Any ideas?
