    I hadthe same fault code

    I had to open up the small cover on the front of the machine.

    Then drain the water in the washer using the drain pipe.

    I then opened the filter cover and found 46p in change in it!

    Also a piece of plastic.

    After removing these item the washer is now working perfectly

Open the small flap at the front bottom right of the machine. DONT unscrew the circular white knob yet!!! Use the small black hose to drain the machine into a tray, by removing the small cap on the end of the hose. You will have to use a tray, rather than a bowl because the hose is only short, and keep emptying the tray.(put a washing up bowl next to the machine, so you don't have to carry the tray.) If water does not come out of the hose, then gently unblock it with a piece of wire or fine knitting needle. When water finally stops coming out of the hose, it is time to gently unscrew the white knob anti-clockwise, and pull it forwards. Now you can clear the debris out of the pump rotor, which is behind the white knob. Check with your finger that it can rotate freely, then replace the white knob firmly. Make sure the small cap is replaced on the end of the hose, clip it back into place and put back the cover panel. If this doesn't work then there is a blockage deeper in the machine, and dismantling will be required. Good Luck!!

    I have this error on the display too. If I turn the knob on the rigt (the grey one) for 15' left, I can't pull it out. What am I missing here? Usually it went smoothly.

The Manual states

    Very good instruction, but in my case it didn't help. I removed the white knob and there was no debris to clear. Instead in the channel/pipe (a bit in to the left) from where the water comes down to the pump rotor there is a coin. I can reach it with my fingers but I am unable to pull it out. I have tried with different tools without any success. The question I have: Is it possible to remove the low part of the front panel in order to access this channel/pipe where the coin is? There is a screw to the right of white knob. When I remove this screw the right part of the panel is lose but the left part is stuck and I can't find any more things to unscrew.

This can also mean that the waste is blocked as i found out today. There was a twist in the waste pipe stopping the water leaving the machine so don't forget to check this also.

F18 is a drainage fault.
The appliance has a set time to drain if it doesn't drain within that time F18 appears in display

F18 error?
First do what is suggested above.
Switch machine to off.
Then switch to drain. 1 min later it should finish.
Remove the white cover bottom right.
Drain excess water into low oven dish by pulling the plug from the little black hose.
Then using long pliers twist the blue\white circular anti clockwise. It is likely to be very stiff so be gentle or you'll crack the plastic. Clean this out. You'll find something in there. Check the little impeller at the back can turn.
Run a short cycle.
If you get another F18 error it's likely that you need to pull the machine out from the wall. Check the drainage hose where it connects to the outlet pipe. If it's full of fluff (and it stinks!) you've found the problem.
Clean it thoroughly. And the outlet pipe if you can.
Run a cycle and the problem should be gone.

Looks like the pump just needs cleaning out (service flap on front). I have not tried this yet. Ours has the same error. I got this info from someone else, but it's worth a try. Gonna do ours when i get home.

How do I fix washing machine to finish emptying during rinse and spin cycle?

Long shot, but does it fill the same as when new? I would check the atmospheric switch which is a hollow tube that runs down the inside of the drum(not in the wash cage) when the water fills, It pushes air up to stop the fill. It may have gotten clogged. Or partially clogged.

Hotpoint WDL520P Washer dryer Filling up with water as it should during the drying phase untill the end of the cycle when it fills up entire drum with water constantly during this cycle it is constant

The other logical point is that it can be related to a faulty output or error from the program controller output. In some cases choosing an alternate program cycle can confirm this case of faulty cycle patterns.

Flashing F 11, drum spins by hand.unplugged for 30 sec and plugged back in started to fill then stopped .flashed F11 again

The F11 error can be difficult to resolve even for us technician's.

The F11 error occurs when the central control and motor control don't talk to each other.

If one of the controls was actually bad then I'd expect to see the error code every cycle. If it does, start by checking all the wiring connections from the panel to the CCU. Post back your results.

I was washing towels on cotton (1) cold water , at the end of cycle during drying a F-02 keep flashing on the control panel. This is a new machine used about 3 months

F02 Is a suds error code or water is to soapy.You need to use the E A type soap.

Try running the machine on rinse and spin.And then go through a normal cycle with no soap.

Washing machine displays an LF error code. Started last week during whitest whites cycle in rinse. I cancelled and just did rinse to finish my load. All other cycles worked and yesterday all started...

LF = Long Fill

LF flashes when the water level does not change for a period of time after the valves are turned on OR water has disengaged the basket but control does not detect a water level change.
Is water supply connected and turned on?
Are hose screens plugged?
Is water entering the tub? If so check pressure hose connection to machine/motor control.

Flashing F what is this

This is usually too much detergent or severely out of balance load. Unplug the washer, this will allow you to open the door to re-balance or eliminate very heavy items from the drum. Close door re-plug and restart machine. If this doesn't do the trick repeat the unplug and reset the dial to rinse/spin to clear excess detergent once finished restart normal wash cycle.

Drum will not spin

I am the new owner of a used Asko Cylinda 10504.
The last owner briefly demonstrated the washer starting a wash cycle and entering the agitation cycle of the wash before stopping and pumping the water out and spinning in a final end cycle. I bought it. I had the machine installed turned it on and cannot get it to go through the wash cycle. After starting at #1 it goes through a perpetual spin cycle of sorts--water and soap soaking the drum and laundry but not enough water to fill up half way or less. It stops at number 4 on the program knob sits on a red dot (next to the #4) and does nothing. I then manually move it to the next cycle and it repeats the spin cycle again until I have advanced the program to the end. No wash cycle no rinse cycle. Nothing. When it advances to the red dot I wait for at least 5 minutes before manually advancing the knob. The instructions say that I should get the water pumped out by turning the program knob to #7 or #9 but in both cases it just spins and does no empty or finish in the end spin cycle of several (9?) minutes. Nothing but banging and spinning. The water seems to get into the drum as well as the detergent but nothing else is happening.
No mater where I start the program it spins and sloshes soapy water, pumping almost nothing out.
Any suggestions short of putting it on the curb or paying a kings ransom to fly a tech out to look at it?

It seems that it is repeating the same brief cycle over and over. During the move to my house the electronics re set(??!?!?) and now need to be set to the normal mode after being re connected?
Can you help?
