Hotpoint WM72 ‘check drain hose’ error

[fatbill]

Here’s one!
Went to a Hpt WM72, flashes E15- check drain hoses. Checked – pumped out fine, no water left. No blockages in sump or hoses. Pressure switch seemed ok. No blockages in pressure chamber,hose or switch. Fills, washes, heats, pumps out, and then the error is reported.
Tried ( brand new from stock ) , control board, power board and even pressure switch. No better. Checked all associated wiring, ran wet test, no problem found. I’ve been doing this job 30 years, and this one isn’t going to get by!!
Anyone seen anything like it?

Bill 😥

Don’t fret yourself too much on this Bill, I’ve come across this too and in my case it was a gents hankie stuck between the inner/outer drum that ‘sometimes’ blocked the sump outlet (causing the E15 -Pump time-out error) 😕

Take the front drum plate off and have a look inside 😉

Didn’t this pop-up a while ago? Turned out to be an earth leak on the heater IIRC.

Yes, after youve stripped the machine looking for blockages and eventually getting round to meggering the machine its more often a earth leak as stated.. .. On the heater, attributed to the drum support breaking and cutting into the heater.
When you spin the drum by hand you cannot always tell the support has cracked, but you can with a load when starting to spin.

This is now quite common, I guess its an age thing..
