Pump not emptying on WMA74

Sound like it could be some "dirt" in the "air-trap-tube", so the machine dont get the signals that says it's empty. This also can also make problems for filling. This "air-trap" is the plastic tube, mounted upwards on the bellow hose, between drum and pump.

Could also be a pressure switch, or pressure sensor problem, but this is not very common:)

This condition is commonly caused by:

- Drain pump jammed

When you wash your clothes, any small objects (e.g. hair pins, coins etc) are flushed down the drain pipe but often get jammed in the drain pumps impellar (this is the tiny propeller on the pump).

Firstly, place a bucket on the floor....then lower your drain hose (from your tub) into the bucket - the gravity will naturally drain the water into the bucket. Be careful to raise the hose and empty the bucket each time, until the machine is empty. Remove any wet clothes from machine (you will need the bowl to be emptied).

Once empty, you can now check the drain pump.

Turn the machin off at the power.

Locate the drain pump cover (usually near the drain hose, on the back or side). Place a large towel on the floor beneath the pump cover (as remaining water will escape onto the floor). Unscrew the drain pump cover and allow the water to drain (if your pump cover contains a filter, then clean everything from this filter).

Then, look inside the drain pump cavity for anything obstructing the little propeller (remove any objects). Insert your finger inside the cavity and rotate the little propeller - you should feel a resistance, similar to a rubber band.

Re-install the drain pump cover (or filter) and ensure it is sealed properly. Turn ON at the wall.

Fill your bucket with water (from tub) and pour into your machine.

Turn machine ON, and select the last SPIN (or drain) cycle and check if machine now drains correctly. If ok, then problem now solved and you can put the clothes back into the machine for a final rinse/spin.

If machine still not draining after inspecting the drain pump, then you may have a suspected faulty drain pump - a technician can run a diagnostic process on your machine's control pad to find the diagnostic codes.

Please do let me know, if the above process helps you solve this.

This is almost certainly the filter to the empty pump blocked. When you power up the machine, the first thing it does is make sure there is no water left over in the tub, if it can't evacuate any water it finds there, it won't go any further. Same on a spin, if after a set time the water hasn't emptied the empty cycle will stop but the spine cycle wont start because there is still water in the drum.

Locate and clean your empty pump filter.

Okay .First you need to say if the pump is working or jammed if you have cleaned the filter then its possible the pump needs replaced......

On F&P machines the inner tub floats away from the dog clutch allowing the agitator to wash without attachment to the drum. When you empty the machine the inner drum settles back on the dog clutch and can be engaged for spinning. A loose drum when full of water is probably not a fault..
37 error is pump fault. Water level not changing.
The pump may be blocked/jammed and be overheating, or it may have failed.
You'll need to unplug the power supply at the socket.
You'll need to empty the machine.
When the water level is low you can lean the machine back to access the pump motor under the tub. Turning the fan blades can sometimes dislodge the obstruction. If the fan turns freely retry the spin mode to empty the machine..
If the pump is jammed you'll have to remove it and clear the port.
Make sure you've emptied the machine as any water left in it will run out when you remove the pump.
carefully study the pump before removal. Take note of the latch which locks the pump in position. Earth wire to open spade connector. Power wires to pump via plug. Remove and clean. Replace and test.
If the pump still overheats it should be replaced or it will damage other components. The pump resistance should be more that 33ohms..
F&P reccommend pump replacement if less than 33ohms.
Good luck.....Nomess

this machine will not spin until it is empty of water. it sounds like your pump is jammed. first- empty water by hand then tip machine backwards so you can look underneath. only tip it back enough to look underneath. on the front right of the machine you will see a black or red fan, that is the pump. turn the fan clockwise then anti clockwise and hopefully that will loosen up what is jamming the pump. put the machine back on its feet and turn it on. advance cycle to spin then push start. it should start draining the rest of the water out and start spinning. please reply 4 more help

Float valve is jammed.

Look inside the machine on the floor will be a small float valve. Looks like a small upside down cup. Lift it and clear anything from underneath.

The valve is a safety feature to stop the machine from over filling. If anything gets under the valve it will jam open and stop the machine.

Not working?

Check for a clog internal or external.

Scoop as much water our as you can. Open the cover on the floor of the machine. Usually just turns and lifts out or snaps out some are screwed in. Take your time and try not to force anything. Look for a clog there.

Check for clog in the drain. The dishwasher will connect to the drain under your sink and run either directly to the drain or into your disposal unit. Remove open the connections and look for a clog. Clear if necessary.

Not the clog?

Water is pumped out by the machine via an internal pump located under the base. If it fails the water will collect until it trips the float valve. First scoop out all the water from the machine and run it again. If water comes in and it runs to the point it fills again and trips the float then either the pump or timer is faulty.

Pump check.

Remove the machine. It will be held in place by screws directly into the counter top. You may have to lower it to get it out. The front feet turn with a wrench to lower.

Turn off the water supply. Run the unit again until you get to the drain cycle.

Connect a test light or voltage tester to the terminals at the pump. Check for voltage at the pump. If you have voltage replace the pump. If no voltage the timer is faulty.

Timer problem?
Some can be replaced as a unit others are integral to the control panel. Turn style can be replaced. Touch control can not.

Hope this helped you. Please take the time to rate this tip.

I would check to see if the drain hose has blocked.

No test available other than:
Remove pump - check motor will turn by rotating impellor. There is a slight resistance then moves freely, then slight resistance and freely again. This is correct for this machine. worth checking there is no hair, elastic band or other obstruction around the impellor fins and shaft whilst the pump is out.
There is no spin cycle so you have to use rinse & spin, which means if the pump is shot you need to empty the machine each time :(
Worth checking lower filter as stated and blowing down the drain hose whilst the pump is off to check for obstructions.
The resolution to my problem was a new pump - £20.
All working fine again now !

make sure that the drain line is higher than the water level in the tub. If it isn't the water will just drain
