Fisher and Paykel Dishwasher, replacing a burnt out resistor on the control
Module :)

Hi there, The model is DW60FX6X1 - I can fix it if I can identify the R7 resistor on the Control Module
I can’t make out the bands as it burnt out after a power cut

Anyone have one they can send a pic through?

Would be an awesome help - $230.00 To replace the module Vs 1-3 bucks for a resistor :)

You should be asking yourself why the resistor blew and investigate in that area.

Most of the posters in this thread are just like chimpanzees on MDMA, full of feelings of bonhomie, joy, and optimism. Fred99 8/4/21

Was a faulty bracket 😁 (and focus too from the look of it)

As has been suggested already, you have identified the symptom, now what is the cause.

Why did the resistor fail?
What further damage did it cause when it failed?
What damage ($) will be done if you get this wrong?

Thanks for the reply’s!

The resistor that’s blown is straight off the power supply in the circuit, the first component in line.

It blew out after a powercut in a rural area so most likely a power surge.

Nothing else on the board looks damaged

If I can’t fix it It would just mean buying the complete part.

Anyhelp to identify the resistor would be hugely appreciated :)

I presume F&P support won't help? Maybe the worst could be you buy a spare board, find the resistance of that component and return the spare for a refund?

A bit of a long shot. Have you tried looking on parts sites / trademe etc to see if they have an image of the item with enough detail to make out the value from the colour bands?

If the resistor is straight off the mains power it may be a current limiting resistor in series with voltage dropper capacitors to some lower voltage circuit.

If it is indeed a limiting resistor it is likely only few hundred ohms, but must be a resistor that has a very high peak pulse power rating and high voltage rating.

Under mains transients these sort of resistors may be subject to over 650 volts for brief periods and can be subject to peak pulses of a couple of kW.

I see from one of your photos that there is a large area blown out of the side of the resistor... an indication of high pulse overload.

Have you checked your security lights and LED light bulbs for failure? These may also have suffered mains transient failures.

Had an extensive search for a spare part or a photo online!

Also tried to get a photo of part from F&P but they only sell it as a sealed unit :( not willing to open it for me..

I’ll try a local appliance repair Guy,

Thanks heaps for all the comments :)
