Water wont drain out of the dishwasher.I have checked the filters and all blockages.When you blow into the drain pipe it is blocked

Well it is a drain blockage code. Check the pipe. I had a blockage caused by the stalk off an apple and an accumulation of lint!

Hi the main reason for this is that the outlet pipe is blocked or the filter at the bottom of the machine is blocked the way to test this is to blow down the water drain pipe to see is its blocked you'll need plenty of puff alternatively the water pump motor is blocked or burnt out it needs unblocking or replaced. I hope that helps you cheers eric

Can you hear the pump trying to drain it? If you can then you have a blockage. Try blowing hard down the outlet hose, what happens? Have you checked all filters?

Hi,

Here is a tip that I wrote that will help you with your dishwasher not draining problem...

Dishwasher Problems - Water will not drain out

Hello,
You seem to have a blockage,have you checked the filters lately.Also check the drain hose and the pipe that the drain hose goes into,if they are clear then the blockage is down in the bottom of the dishwasher in the pipes or the drain pump.

Hope this helps.

fish bone in the impellor

Hi try checking if the drain outlet pipe is blocked by this I mean blow down the pipe it takes a bit of puff but if you cant then there's is something blocking the water from getting out, either a blockage or the water pump not working enabling the washer to start the new cycle
I hope that helps cheers eric

I've had this problem a couple of times with my dishwasher. In both cases, the cause was a shard of broken glass that had managed to get past the filters and jam itself underneath the impellor. Hard to see, but easy to fix. First ladle out the water.
Pull off the lower rotor arm, unscrew the filter and take out the filter bowl, tray and cylindrical filter. Get as much water as you can out of the filter cavity.
Then, using a Torx-20 driver, remove the screw holding the impellor cover and lift the cover off. (this is the small bit of plastic at the left end of the filter cavity.) Check whether the impellor can rotate freely by spinning it with your finger several times - if it jams or grinds, then there's probably something jammed under it. (It may seem to be fine at first, so do check thoroughly, as any debris can move around with the water flow and only jam occasionally) You may have to use a cocktail stick or similar to poke out anything that's stuck underneath.
Glass is a particular problem, since it's almost impossible to see when there's any water around (it's easy to cut yourself too!)

Anyway, that's worked twice for me now - and I didn't have to even move the machine out of its cupboard to fix it.
Hope that helps.

it should have water just below filter tray, if it does not actually empty then you have a blockage ,remove left side panel to gain access to drain pipe and side chamber. Regards Engineer

DEFINATELY A BLOCKAGE OR RESTRICTION ON THE DRAINAGE SIDE.DISCONNECT THE PIPING COMMING FROM THE DRUM TO THE DRAIN MOTOR. MAKE SURE ALL IS CLEAR. REMOVE PUMP AND OPEN PUMP HOUSING TO INSPECT.(BLADE COULD BE LOOSE ETC). FINALLY RUN WATER INTO DRAIN PIPE AND EXPELL WATER BY BLOWING HARD.IF BLOCKED, RECTIY. REASSEMBLE AND TRY AGAIN.
