washing machine main board

Hello,

Without the exact washing machine make, model number, and the board number printed on the PCB, it isn’t really possible to state the resistor values with any confidence. On washing machine main boards, burnt or bowed resistors are often part of a power supply or drive circuit, and fitting the wrong values can cause further damage.

A few checks to help identify them:

1. Get the full details - Please post the appliance make and full model number from the rating plate. - Also post the board/PCB number printed on the board itself, and clear photos of both sides of the PCB.

2. Check the resistor markings - If the bodies are not too badly damaged, look for coloured bands or printed numbers. - A close-up photo of the resistors and the surrounding components may let someone identify them from the circuit area.

3. Inspect for other failed parts - Bowed or burnt resistors are often a symptom, not the root cause. - Check for a shorted triac, failed diode, blown switching chip, damaged tracks, or bulging capacitors nearby.

4. Compare with the circuit position - If the resistors are in the mains input/power supply section, extreme care is needed. - If they are near a motor triac, heater relay, or door lock circuit, their values will depend on that part of the design.

5. Do not guess the values - Replacing them by trial and error can destroy the board beyond repair.

Important: isolate the appliance from the mains before inspecting or removing the board. If the damage is in the mains section, I’d strongly recommend a qualified engineer or an electronics repair specialist.

If you upload clear pictures and the model/board numbers, I can help narrow it down.
