Hi folks my model is DVH610JUI and it has an 03 fault but the heater tests ok at 30ish ohms the d/w emptys, fills then comes up with 03 (lights 1&2 flashing along with blue start light) sort of scratching my head now but thinking pcb. At least I can access that.
Cheers Johnnyboy
cannot say for certain whether your model is the same, but some dedietrchs have a seperate door microswitch wired in circuit with the heater, dont ask me why but worth a check.
As mentioned above there is a door switch that controls the model on this model, so worth checking. If you require a service manual on this model PM me your email address I will send one over.
