Lg Intermittent Draining

[mervyn]

Hi,

My LG WM12220FD washing machine drains intermittently. I have stripped out the pumps and cleaned them (one was particularly gunged up) checked for open circuits,which were fine, and cleaned the hoses.

The machine is still only draining intermittently although if I quickly switch the plug on and off the machine will then carry on as if no fault had occurred. The only thing I can think of is that the control board may have become faulty?

Any advice please?

Thanks

Mervyn

Intermittent faults like this are usually difficult to diagnose. Check the pump isn't cutting out. Also check the sump hose for obstructions and make sure if a plastic ball is fitted that it isn't covered in gunge which can make it intermittently stick. Other possibilities are a small coin or buttons flipping around and acting like a butterfly valve. Check everything in my article not pumping water out including the links within it.

Hi,

Thanks, I did read it but will re-read in case I missed something. I think I will have to take the machine apart again and re-check everything. Being pensioners I would hate to buy the two pumps required and then find it still will not work ;-)

Yes, buying parts speculatively often costs more than paying an engineer. It's crazy how many people buy one part after another and it drags out over weeks and often give up having wasted a lot of money and time. If the fault is very intermittent it's going to be hard, but if it is playing up fairly frequently you need to observe it carefully when it stops pumping out. Listen to the machine, has the pump stopped running? Is it sounding different? It's definitely worth taking off the sump hose (Black hose leading to the pump) and maybe even the drain hose to see if you can find anything inside them.

I may have made a huge mistake here.............My mind must be going ;-) when the fault occurs the pumps do not appear to be actually running! It is only when I switch the plug off and then on again it seems to spur it into action and then it pumps out and carries on with the set program.

There should only be one pump responsible for draining the water. If it actually stops then it could be cutting out. If so it may be very hot (be careful) which might imply it's faulty or got an obstruction inside. However, small objects like hair grips or elastic bands can slow a pump down and make it overheat. Check the pump doesn't have anything inside it especially wrapped around the impeller.

Hi, Did you find a solution to this?

Hi yes,

I just replaced the pump & housing
