Hoover HDPN 1S543PX-80 Error 03

[Murphwiz]

Hello, I’ve got problem with my Hoover HDPN 1S643PX-80 Error 03.
it shows error 03 on drain, drain pump up runs, and I’ve pulled hose out and verified it actually drains, but put won’t stop.
any ideas where to look for the problem?
recently every few washes it does leave a stale smell, so it could be retaining water I guess.
any tips or pointers would be great, before I battle it from under the counter.

Thanks Dave, typing error on my part, but I can’t update title, it should be:

Hoover HDPN 1S643PX-80

I checked and E3 is a drain fault

its either a blockage in the drain or in the pressure system that detects the water

Many thanks.
I pulled drain pipe and did a quick rinse cycle, plenty of water came out, then stopped but pump carried on before E3 beeped.
so guess pressure sensor thinks water hasn’t finished draining.

[Murphwiz]

Is there a spec for the sensor, so I can check it?

[electrofix]

the sensor is air operated so first check for blocked pipes

switch part no should be 41030820

if you google it you can see what it looks like

Many thanks, will take look.

Removed sensor, there was a little water in the pipe.
gently blew into sensor, can hear switch move.
with a multimeter, no pressure, it’s open circuit, blow into sensor, changes to 0 ohms.

blew into sump, that seems clear, blew down outlet hose, that ‘blocked, removed hose, appears to be a one way valve on the body, so appears normal.
any thoughts.

[electrofix]

have you tried it again after that ?

Dave

[Murphwiz]

Not yet no, just debating what else could cause it.

[Murphwiz]

Runs couple of cycles, seems to be working fine.
is the water in the pressure pipe enough to fool the switch?

[electrofix]

could just be the switch stuck and you have freed it

Dave

[Murphwiz]

Thanks for the pointers.
will give it a couple more runs, and stick it back under the worktop.
