Re: Belling problems..
E3 = Not Heating
Check the obvious heater o/c etc
If heater ok, change the pressure switch nearest the front kick panel or you can try the adjust 1 complete turn clockwise, this will bring in more water which can be a problem on these.
Depending on serial number there is a small pressure sensor on the tube connected to the floe through heater this also gave problems and stopped the heater from working. And yes its Chinese!
