Dishwasher code E11 Hotpoint Hydrocare 7883P

[JohnD]

The machine would not start for several attempts - after the prewash it refilled, then it stopped with no progress markers on display.

After several attempts, it then performed a wash, but while draining out the final rinse it went "bleep bleep" repeatedly and displayed "E 11"
The pump continued trying to empty it even after it was emptty, until I tuirned off the on/off switch.

Although badged as Hotpoint the internals look just like a Bosch to me.

Does anyone know what E 11 is?

E11 - Heater timed out. The heater has not reached the required level in a certain amount of time.

Doesn't quite answer the pump running all the time though. Have you checked to see if the base is flooded?

 

[JohnD]

Thanks for that.

This one has on open base (not a tray) and has not been weeing onto the floor. The E11 occurred after pumping out the final rinse so perhaps it was trying to turn on the heater for drying.

During the unsuccesful washes earlier today, the display went blank after filling up with water for the wash, and I was wondering if this might be caused by a voltage drop when it tried to turn the heater on.

Last week I had trouble with it not pumping out after doing the final rinse. It has an electronic control board (now withdrawn) so I suspect it may that breaking down with age. It is about 10 years old and on its third board (the others were replaced under contract when the LCD display went dim, so I am guessing dry soldered joints).

Do you know anyone who might service the PCB? Is there a way I can test if that is at fault (I have a DMM but no Electronic skills )

If not at this age I think it will be for the dump. A pity as it has been in infrequent use and looks fine otherwise.

Two companies that might be able to help are EMW and QER.
However, it may be worthwhile going over the solder joints on the board(s). Tedious job but if it's a dry joint then that should sort it.

 

[JohnD]

Thanks, I can do that.

Small iron, well tinned? Do I need to flux the old joints or add a little extra solder, or do they just need to be heated enough to melt and reform? (this is not something I normally do)

Ta,

John

Edited: p.s. I can't find those companies on the web. Do you know what the initials stand for? Tks.

Normally just enough to melt and reform. The odd one might need a small amount of solder.
Definitely a small tip and kept well tinned.
I'll get the phone numbers for EMW and QER if resoldering doesn't work.

Thanks, that's great!
