Candy CDPH 2L1049 beeping and flashing all lights. Panic mode.

[MArk31415]

Hi Dishwasher is 1 week out of warranty!!!

Taken the side off and run it up. Seems it
Initially purges – Good
Starts to fill – Good
After a few seconds pumps out – Bad
Once pumped out Flashes all lights 4 times and beeps. – Bad

Suspect flow sensor is saying water is coming in but level sensor is not happy so doing a panic purge.
The water matrix has the flow sensor but I can’t see the level/pressure sensor. Anyone know where it is as it’s not on the water matrix where I’d usually find it.

Pretty sure these are the same internals as a Hotpoint.

Any tips to fix this. Also any idea how to diagnose the flow sensor… It spins but obviously no idea if the sensor part is sensing.

Thanks in advance,
Mark.

dont think the is a pressure sensor on this one

E40 alarms are all water inlet based
see below

Thanks for the response. This is a cheapo washer so no digital display but flashes all 9 lights 4 times and beeps and repeats until you turn it off. Even if there is no pressure switch I assume there must be some sort of water level sender so it knows when it’s full/empty. In the past I tend to find these level senders in the water matrix itself. Any idea where it is on these Candy/Hotpoint machines?

There is a sender towards the rear of the machine on the pipe that the heater element sits within. Could this be a level sensor?

Machine fills to the point the water is level with the bottom of the cavity. No water flows into the cavity itself.

A lot of modern machines have started using virtual sensors
the flow sensor on the side counts the water in and measures the volume that way
they detect the pump current to determine when the machine is empty

I assume the main wash motor does not start. Have you checked if the motor energises but does not run ?

It goes straight from fill to drain. Does not seem to wait for a pump. Can hear a bit of sloshing from down low. Managed to crack the pressure sensor that sits on the heater element tube so need one of those anyway. That switch was good though. Need to get a replacement pronto so may cut my losses and sell for parts. Bit annoying given it’s brand new but will be expensive to just fire the parts cannon at it.

if the wash pump is not starting then it will seem to go from fill to drain. As the unit finds a fault it will then drain

but these are a low end unit as hoover / Candy have never made dishwashers but sourced them somewhere else and had them rebadged
