How do you clean the filter

More then Likely there is more then just a suds lock small objects can build up loose change all can be in pump housing poss even damaged prop on pump it self need full model # and serial # to say much more

To clean contaminated ISV of Robinair 34700Z, open front lower panel, then slowly disconnect 3 hoses from ISV (Liquid, Air purge and Vapor). Now unscrew ISV tank from machine and then fixed an adapter to Liquid port of the tank to allow all the contaminated refrigerant to go out from tank. after emptying the tank, if possible make vacuum for approx. 10 minute with an external vacuum pump. Replace everything its original location after completing vacuum. Now change spin-on filter (Located on the back side of the machine) and vacuum pump oil. Your machine is now ready to work.
Thanks and I hope this will help you to solve your problems.

it might have blown a track on the programmer if so then you will need a new bold ok

I believe that this is a "Pump Blockage" error. You need to locate and clean out your empty pump filter (Probably behind a little door on the bottom of the machine. You may also need to check the empty pipe and the drain it goes into are also clear. 99% probability of a blocked filter

The filter for your empty pump is probably clogged. The machine can't drain the water in the alloted time because it is draining to slowly through the clogged filter. The machine won't start the spin cycle if all the water hasn't been evacuated. You will need to find and clean out your empty pump filter (Probably behind a little door at the bottom of the machine.

hi, read about your problem. The filter is located at the bottom of the front of washer. If its not visible, remove the bottom kick panel. Three screws at bottom. Take a shallow pan and place under filter. Slowly turn counterclockwise and water will slowly start to come out. When pan is partially full, empty. Be sure to close filter before doing this. Keep up with this procedure until no more water comes out, then unscrew filter and remove and clean. Reinstall and put kickplate back on. Hope this helps.

If ther is no filter at the front of washer, then remove lower rear panel of washer.
Locate and remove large black hose fastened to bottom of drum.
Remove and clean filter inside hose, also remove hose onto pump, and check for obstruction here and in the pump.
Please rate my solution.
Thanks.

I was unable to locate your filter in your machine but if it would help after you clean the filter you could install an inline filter between the valve and the hose. This is an RV filter it just screws on like the hose.

The FP12GKE shows just how easy it is. Any RV filter will work.

Check pump filter located at rear of washer, remove rear cover, locate and remove large black hose, remove and clean filter.
Please rate my solution.
Thanks.

Remove the bottom casing covering the front of the machine just above the floor. Unscrew the circular cap SLOWLY- beware of vast amounts of water escaping though!
I had to use a low height roasting pan to catch water, and just unscrew the cap enough so as to control the flow of water, and enable to empty water away until its all gone. Incidentally, an old hairgrip was found to be the cause of my problem.
Confusingly, "clean pump" meant clean filter!
