Beko WM7127w wont drain - ordered a pump.

[rigby1987]

Hi there I've had a problem with my washer it wouldn't drain and there would be a pool of water left in the drum.

I've been googling my problem and was directed to change the carbon brushes , but I've stripped it down and the brushes are worn down but not really bad I've added some pics .

So my next thought is the pump so I have ordered this part from you , I've ran the test on the machine where you hold start before turning on and it spins and it fills and spins the other way but I press start again and I'm asuming that the next test was drain but it did nothing.

If I start the machine on drain mode 2:00 comes up with the play icon but it does nothing so this must be the part I need right ?

I can't afford a new washer so I'm hoping this will fix it ...please could you get back to me and tell me what you think.

Regards , Tomas.

That is what i sent the guy i bought my new pump from earlier today . Since then ive stripped down the pump and tried to look for anything that may be blocking it and i cant find it but the pump its self looks bad. Do you think the new pump may fix my washer ?

 

Also when i start test mode i get E08 code and it spins fine but then thats it , also f3 is lit up on the lcd display.

Hello there. Those brushes look fine. Unless one of them is charred where it runs on the commutator they don’t need replacing. 

Regarding the pump. You shouldn’t just order a pump. But if you are lucky it might fix the fault. The pump might not be getting any power or have an electrical connection fault on the neutral. However, a faulty pump is more likely. To test a pump you should test across the two connector pins with a continuity test meter. If there is no reading and it’s open circuit it’s faulty. If you get a reading then there must be another explanation as to why it isn’t running.

Thanks a lot for the reply , I will test the pump contacts for continuity tomorrow when I get chance , however I have already ordered the pump.

Thanks for looking at the brushes at least that's one thing I know is okay on the machine.

Regarding the pump, if you look at one of the pictures you can see there is a ball thing inside the drain hose that comes from the washer drum if you know what I mean .

Is that meant to be in there? 

Also for when the new pump comes could anyone tell me which way round the electric spade connections go in to the pump I forgot to take a photo of it connected.

If I fit the new pump and it doesn'tfix the problem what /how would I diagnose if there is a fault with the electrics/pcb ?

Thanks again for the help.

I have a multimetre but which setting should I have it on to test it?

Please get back to me.

Hi again i have tested the connections. Have i done it right?

Does this mean its not the pump that is at fault?

Please look at the photo with the connections on , Please could anyone tell me which way they go back in?

Thanks again

The test shows that power will run through the pump ok, so it should at least try to run. It could still be faulty if for example it was physically jammed.

If it just gently hums when it should be running it would show it is getting power and a neutral return. 

The pump is just connected by a live and a neutral and it doesn’t matter which way round they are.

The ball seals off the water in the sump hose. If it gets coated in slime and gunge it can stick to the rubber grommet in the top of the sump hose. This can stop the water from draining out. 

The symptoms would be that you can hear the pump running but water doesn’t get pumped out.

Hello Andy thank you so much for the help so far. I will wait until the new pump comes and try installing that first to see if it fixes the problem. 

I will then get back to you with the results of my findings .

Hi again Andy ,

Earlier this morning I reconnected the pump and tried a quick wash (30 minutes 30 degrees) , the pump now seemed to drain most of the water ( although there was a loud grinding noise coming from it ) , but it refused to do the 1200rpm fast spin at the end of the wash and the 2 old sheets i put in were still kind of wet .

Any idea what this problem may be ? 

I read that if the pump can't drain fast enough that it won't spin fast. Is this right?

If so , it does look like the pump is the culprit.

Many thanks as always ,

Tom

Hello Tom. A loud grinding noise when the pump is running is usually caused by a small object that has got inside and is being tossed around by the impeller. It is possible for certain objects, (especially if made of plastic) to float about up the sump hose or even partially up the drain hose. This means they are not discovered when looking for obstructions. But when the washing machine is in operation again they get sucked back into the pump. It's also possible that a bearing has failed on the pump.

If the washing machine cannot pump out the water fast enough it will usually refuse to spin. It will just click and stop. But it is possible for it to have pumped enough water out to allow a spin, but then cannot cope with the influx of expressed water from the laundry. This would result in the spin being uneven with lots of water being thrown about inside the drum. This could very easily trigger the out of balance system to either abort the spin, or abort the fastest spin.

Thanks for the reply Andy ,

When i got back from the doctors , i tried a 60 degree 1 hour wash , but the drum basically only did half turns for the first 30 minutes and the pump noise was even worse , so I undid the trap of the drum , while it was running and the propeller in the pump was out of its housing , within the pump housing itself as I've shown in the attachments. 

I had to turn it off at 30 minutes remainimg because the pump was just making a horrible noise i know it was that because i could see and hear where it was coming from .

I had to turn it off because I couldn't stop the cycle by the pcb buttons.

I think I'll be leaving it until the pump arrives for now . Does this sound like if I swap it with the replacement it may fix everything?

Thanks for the guidance.

Tom

Hi Andy I missed the delivery of the pump yesterday .I'm going to pick it up this morning so I should have it fitted and tested today at some point.

https://www.amazon.co.uk/Bahco-SL25-Socket-Piece-Drive/dp/B000Y8XCA8/ref=mp_s_a_1_3?ie=UTF8&qid=1538030580&sr=8-3&pi=AC_SX236_SY340_FMwebp_QL65&keywords=ratchet+set&dpPl=1&dpID=51ChZQBLakL&ref=plSrch

Could you possibly look at that link .will that set work for removing the heating element because I wouldn't mind taking a look at it as if it's looking bad I'll change that too.

 

Thanks pal

Hello there. Let's hope all this all gets the fault fixed. Looks like it's been a lot of trouble. The heating elements are usually secured by a 10 mm nut, which can be easily undone with a 10 mm spanner. You don't really need a box spanner for ratchet set for the job.

You should find my article here of great use - How to remove the heating element from a washing machine

Hi again andy, Ive fitted the pump and started a 30 min quick wash , Its at the end of the cycle at 02 mins left and the pump is making a buzzing noise and the washer just keeps spinning on and off. Heres a video and a picture...

I dont know what to do with it now .

:(

Hello Tom. If the pump is making a buzzing noise but no water is being drained out then there is a blockage somewhere, or the pump is not running but if it is a different pump with the same fault then it seems very unlikely that the pump would not be running. The only thing I could imagine is if the pump isn't receiving enough voltage that I have not heard of that before.

However, if there is a blockage somewhere preventing water from being expelled the pump would be making a noise. Did you clean out the sump hose ball that was mentioned earlier that I described can stick and block the water in the drum from getting to the pump? Have you checked for blockages at the end of the drain hose where it connects under the sink at the u-bend? Remove the drain hose and check in the end plus remove the spigot it connects to and inspect that and the u-bend where it connects for obstructions.

It's impossible to hear any buzzing from your video on YouTube because the radio was playing. The first link doesn't work at all. I'm assuming it's on a drain section? No water is being pumped out at all. 

Has the pump got a filter at the front? If so drain out all of the water you can, play several thick towels in front of it and remove the filter. Then put the washing machine onto a spin cycle and see if you can see that the pump impeller is spinning or not.

You need to establish 100% if the pump is running or not. If it is running but not draining then it can only be a blockage somewhere in the system. If it is not running, or it is just humming and the impeller isn't spinning round then it can only be a fault on the pump, something jamming the pump, or an electrical fault somewhere.

Hello again andy sorry for the quick post i was busy , hope your well...

i have checked the sump hose? from the drum and the drain pipe and its a new pump that i fitted so i cant think of anywhere else , ive checked the U bend under the sink all clear .If it is an electrical problem where the pcb isnt delivering enough power to the pump , how would i fix that?

Replace the control board pcb? or the power supply part?

ive recorded a couple more videos and uploaded them to my youtube channel

https://youtu.be/T1rwl24XT-w

https://youtu.be/omAj-n9hI_I

One is of the test mode by holding start and the other is me starting a 40 degree class a wash .

currently were at 1:55 time to go and its still going so ill tell you what comes of it.

Once again , thanks for the help , Tom.

[Whitegoodshelp (Andy)]

Hello. If the fault is that it isn’t emptying the water I need to see it on a spin and drain cycle not wash. And also with no loud radio drowning out the washing machine sounds

[rigby1987]

Hello again Andy.  Washer seems okay now with the pump but now I seem to have another problem.

When the drum is turning and spinning there is like a loud rattling grinding noise. 

I'm guessing this is the bearings ?

I'm also guessing this can't be fixed?

Cheers again . 

P.s sorry for the late reply. 

Tomas

Hello. Bearings can't just go that suddenly. Could some obstruction have become dislodged after laying it down? Also, a metallic grinding noise maybe the motor catching on the back of the casing.
