The function of your water pump is not normal. Check the rubber bushing or the impeller, I suppose they are loose.

Make sure you click helped, if helped that is.

E04 means that you are not draining quick enough, if you are using HE detergant then your drain line is probably clogged. There is a round access panel on the lower right corner of your washer. If you stick a small screwdriver through the tiny little hole on this panel and twist the panel off you will see the drain pump catch. You can twist this cap off by hand and remove all the debris inside. WATCH OUT a lot of water will be coming through.

You need to check the drain pump externally to see if the pumping is good Also remove the drain hose clamps and remove the drain hose flushing to clear off all dirt. Now test using power to see if this works and can be simulated. When refitting, the hose must be tightened properly. If the pump/valve does not work even with power then it must be replaced. If there is intermittent power to the drain valve/pump then the program controller unit is a suspect.

Finally the washer must be placed with a tilt- use a spirit level- so that all water will drain to the outlet port and thereby there is no residual water remaining.

Hi mwilczewsk,

I believe your drain pump filter is just clogged. The drain pump is trying to pump the water out before the Spin cycle, but can't. Usually this is caused by a foreign object that is obstructing the impeller. See my tip on how to access, drain & clean the Drain Pump Filter:

ACCESS, DRAIN & CLEAN THE DRAIN PUMP FILTER

After this, the Spin cycle will run, after the drainage procedure. If it does not, then you may need to replace the Drain Motor. Which is a easy task.

Kind Regards :-)

Hello, Welcome to FixYa. You've stated that the drain hose has been checked, have you also inspected inside the drain pump ? Does the unit display any error code, i.e. E13 or E04 etc ? Also if you could varify the unit is indeed a WFMC6400 before going much further it will save on potential mis-information...its best to be clear from afar. I'll watch for your reply so we can move towards a solution for you. macmarkus :)

There should be a filter located at the bottom right front of washer behind drop down flap or plastic cover.
Unscrew anti-clockwise to remove and clean.

The error indicates that the machine has taken too long to drain the water. Do the following.

1. Switch off the machine and disconnect the mains power.
2. Remove the access panel on the lower right front of the machine.
3. Remove the filter and make sure that the filter is not blocked and is clean and clear of all debris. Clean as required.

4. Proceed by checking the drain hose for proper connection and kinks and make sure that it is not blocked.
5. Also check that the main waste drain pipe, if you use one, is not blocked and clean if required.
6. Reconnect the power and switch the machine on.
If the problem persists then do the following.
7. Switch off the machine and disconnect the mains power.
8. Check the electrical connections at the pump and make sure it is operational.
9. Remove the connecting hoses, and expect water to drain out and make sure the pipes are not blocked with debris or any object blockage.
10. Makes sure the pump appears clear and that the impeller looks in good condition.
11. Reconnect the hoses and then reconnect power and switch the machine on.
12. If problem has not been corrected, then remove the pump and check that the drive coupling to the motor is OK and that the motor turns OK. If all is well then replace the pump.
