Re: Hotpoint FDL Leak Power Trip

So I was receiving error code E4 Heating phase timed out

Heater open circuit
NTC thermistor detached from casing

but the heater was working until the drying phase.

Also the motor was faulty and only pumping water intermittently.

I checked the NTC thermistor which is connected to inlet pump on this model. I also disconected the wiring to the PCB of the heater power cable and wire brushed a bit of rust around there.

I replaced both motor and heater. Heater was less than a year old so got that done through warranty.

With new motor the RCD was tripping on the heater drawing too many amps. Maybe thats the cause of e4 was a thermostat time out.

All working now. Hope this heater doesn’t fail in less than a year.

Heater was showing continuity but insulation / earth leak causing rcd trip + drying phase failure.

Re: Hotpoint FDL Leak Power Trip

So when Ive disconnected the cable to the heater the dishwasher powers on.

However when it is connected there is a circuit break as soon as I put the plug in.

What could be the reason for this if the heater gives out a resistance and looks to be working normally. Is it an insulation problem? The reading was a little high at 38ohms.

Re: Hotpoint FDL Leak Power Trip

Thanks

Ive purchased a motor for 46 so it’ll be worth it even if I get another two years from it.

If the breaker trips again the heater is still within warranty, as ive identified that is the cause as no trips when I unplug it. (motor and heater can trip the heater connection)

Ill update the thread when Im finished no doubt it will help someone.

Hi Dave

Thanks so much for the reply.

So the cracked magnet would cause the breaker to trip?
