ISE W1607W Spin fault

[BryanC]

We have a fairly early ISE W1607W which has given good service over the years however just recently it has developed a spin fault. The machine runs through the normal wash cycle ok followed by draining and the drum slowly rotating prior to spin. As the drum starts to increase speed for spinning it suddenly cuts out. It attempts to spin again a few times after short intervals with the same result before it stops altogether.
I have checked that there are no blockages in the drain hose and pump housing and the pump appears to be working ok with a good drainage action. I have checked the pressure switch and as far as I can tell it appears to be ok (clicking when blown into and has open and closed circuits operating. I have also blown the opposite way through the pressure pipe to ensure no blockages in the reservoir).
Any suggestions out there what might be the problem?

A question for somebody more knowledgeable about washing machines than me! If I can ascertain that there is nothing wrong with the Pressure Chamber and rubber tube that connects from the Pressure Chamber to the Pressure Switch, could I test the operation of the Pressure Switch by disconnecting the tube from the switch and running the machine on Drain & Spin? My thoughts are that it will drain (which I know works) and then spin? If the machine spins successfully then I can just replace the switch!

well if the switch is giving the wrong signal then it will continue

you could try a long shot

on Hotpoint machines the pressure switch can be calibrated by adding a couple of litres of water, then selecting a drain programme and let it keep going till the end

Thanks for your reply Dave. Bizarrely the very next morning the machine worked perfectly with a full wash load (‘er-in-doors thought even without a spin she could hang the washing out and let it drip-dry), so I stupidly thought the machine had rectified itself!! This morning the fault occurred again, draining ok, trying to spin and cutting out just as it tries to get up to speed. Panels off again!!
I tried your Hotpoint trick of a couple of litres of water but the fault still occurred when it tried to spin. Tried my trick of disconnecting the pressure pipe but still no success.
I put the machine into the test program and drain and spin seemed to be ok, but run it through a cycle or part cycle and the problem returns, cutting out just as spin seems to be ramping up to full spin speed.
Just so frustrating, any more suggestions Dave or anybody…. getting to wits end here, just as well it is summer and missus can hang washing out dripping wet!!!

well i assume on test you have no load in it

Dave

[BryanC]

Hmmmm…… correct !

Try it on a rinse & spin programme a few times without a load. If it spins perfectly without a load every time you try it and also spun with a full load it would suggest an OOB condition. An out of balance load will give the exact symptoms you see but if you allow it to fully complete the programme after this occurrence you should then get ——— three dashes in the display. I have the same machine and did change the belt a couple of years back due to persistent OOB. It did seem to help to reduce the incidence.

[BryanC]

Thanks Iadom and Dave for your helpful and knowledgeable responses. I have taken the plunge and ordered a replacement drive belt off UKWhitegoods to see if that helps to resolve the problem. Is there anything particularly tricky or that I should look out for when replacing the belt. I promise not to fit it with my fingers crossed!!!

[iadom]

Compare the new and old belt to see if there is evidence of belt stretch, refitting is very simple but the new belt should be very tight. Under loading with single heavy items such as bathmats very large towels etc or mixing one heavy item with smaller, lighter items can all cause OOB conditions. Observe the door as the machine starts to ramp up to spin speed, is there a lot of side to side movement? Ideally the door should be fairly central and steady with a correctly balanced load.

The plot thickens! Having received a replacement belt I hadn’t fitted it as the machine appeared to be behaving itself until last night. This morning when I woke up I could hear water running. The machine was constantly filling with water while immediately draining it out again. The pump wasn’t operating, just water flowing in and out. This appears to be a new symptom!! I pressed the power switch in an attempt to stop the machine and the water valve shut down and the pump kicked in and attempted to complete the cycle…. it finally completed a proper spin (1200 RPM) but only when the memory was cleared and spin and drain selected. Panels off once more and I took the opportunity to fit the new belt. There was definitely evidence of stretch in the old one. I also took details of the pressure switch in case this turns out to be the culprit but can’t find a match on-line. It is not the common circular one that you often see but a more elongated switch with 2 thin wires and 2 thicker wires connected to it. The refence on the switch is 8089765. If I could obtain a replacement I would probably fit it just to eliminate the switch as being the culprit. Any further advice or help anyone please???

Was the machine originally switched off overnight? You say the pump wasn’t running, if so how did the water get out of the machine? Where any of the controls illuminated when it was filing and emptying? I never had to change a pressure switch on Any ISE 10 machine at all. If it eventually stopped filling as you switched it on and off that would generally rule out a sticking fill valve which then points to an electronics failure. If the drain outlet hose is set to low or has slipped over at the back that would allow the machine to drain without the pump operating otherwise the water can’t get out without the pump.

Hi iadom, we really appreciate your assistance.
The machine was set on a delay wash to come on early hours of the morning, which it did. When I came to look how it was doing it looked like it was on the final rinse and spin but the machine was filling but I could also hear water flowing into the waste pipe under the sink but the pump was not running, all I could hear was water entering the machine and flowing out to the drain (the outlet hose was still securely located in the waste stand pipe) until I intervened and pressed the power button at which point the inlet valve closed and the pump started pumping. My guess is that it had been dumping water for a couple of hours. Could the water just “overflow” through the non-running pump and out to drain if the inlet valve was stuck open? All normal lights were illuminated and I think the display was stopped at 22 minutes remaining then proceeded to gradually count down after I intervened while it attempted to finish the cycle, but failed to do a final spin (again) until the memory was manually cleared and spin and drain manually selected… then it completed the cycle.

It’s difficult for me to speculate without seeing your installation set up. It is possible for a machine to syphon if the outet hose is either to far down the standpipe, sealed to the standpipe or the standpipe has dropped over a little. The end of the washing machine waste pipe should not be sealed to the standpipe, there must be an air break to prevent syphoning. It is possible for an outlet hose that is a tight fit into the standpipe to become ‘sealed’ to the standpipe with gunge.

To be perfectly honest I would never leave any appliance that uses water on delay, or running overnight. 🙁

not to mention the possible fire risks of doing so

Thanks guys, I take on board your comments about delaying the wash.
As far as syphoning is concerned, if nothing else but to satisfy my mind, I re-checked the location of the drain hose in the waste stand pipe this morning and all looks good with plenty of air space, no gunge etc. and located correctly. I am putting the draining problem down to a one-off, possibly caused by the the original fault of not completing a full cycle correctly without intervention of needing to clear the memory and manually selecting spin & drain. The spin action obviously works but not as part of a full cycle. Unless you guys have any further thoughts of things to try, the next load of washing is due to be done tomorrow morning so I will monitor the cycle and report back. Thanks again.
