Hotpoint wmf940 washing machine not filling with water

[B3nxr]

I have a hotpoint wmf940 washing machine, last weekend I changed the sink trap under the sink because it was leaking. So I connected the washing machine outlet pipe back onto the trap and did a wash. I came back intot the kitchen to find the washing machine display lights flashing with error code f 05. So I looked the code up and found that its a blockage. I took the outlet pipe off the sink trap and no water was coming out, this Was because the new
Sink trap comes with a plug in the end just incase it isn't needed which I hadn't removed. I then removed the plug and the water poured out. I then tried to wash the clothes again because they had been sat in water for a while but water would not enter the machine. I turned it off and left it overnight, meanwhile i searched the internet for possibilities. The first thing I did was change the water valve and then I changed the pressure switch, neither of these have worked so I'm stumped now.
There are no lights flashing now and no error code, the washing machine drum does still spin, there is a humming noise when water should enter and I have checked the filter for blockage

Any help would be much appreciated, I hope the description is understandable
Thanks

If there's a humming noise that means the water is not switched on. Does water come out of the inlet pipe when it's unscrewed from the back of the mc.

The water feed is turned on and works fine. If I unscrew it water gushes out at quite a high pressure

Did you tilt the mc when you moved it. Cos it can upset the Presure switch. Was it a liner Presure switch you bought. Poss blue in colour.

 

[B3nxr]

Yes it was a liner switch in blue. Exactly the same as what is on now

 

[rocks1]

Right. Pour one litre of water into the drum with mc switched on. Then unplug the pipe on the Presure switch for 1 min. Then reconnect see it it pumps out and fills.

I will try that now

 

[B3nxr]

I tried that. No water was pumped out and made a loud noise like it shouldn't really make

Is the pump running. It should have pumped that water out if not there's a blockage somewhere in the pump.

 

[B3nxr]

How would I know if the pump is running? Could there be a blockage because all that blocked it was water?

 

[rocks1]

Undo the filter and look in the pump. Is the impeller spinning round. If you put water in the drum it should have pumped it out. Look at the pump first.

 

[B3nxr]

The filter and the front of the machine at the bottom?

 

[rocks1]

Yes , pump is behind it.

 

[B3nxr]

I've undone the filter and water is pouring out, obviously the water I previously poured in

It should have come out the waste pipe. You got a blockage somewhere.
