Bosch wvg30461gb Won’t start
I have a Bosch wvg30461gb. It locks but doesn’t start. There is no beeping or any drum or pump action after door locks. I can’t hear any relays in action either after the door locks. I’ve checked the pump and it’s not blocked and isn’t open circuit. Would I be right in assuming a pcb is at fault

This thread was marked as solved. Here's a summary of the problem and the fix, generated from the discussion below.
Bosch WVG30461GB locks but will not begin a cycle
- The problem
- Bosch WVG30461GB washing machine door locks, but the programme does not start. There is no beep, drum movement, pump action or audible relay activity after locking.
- Likely cause
- The accepted reply says a PCB fault is possible but not proven. The stronger supported diagnosis is that the circuit is stopping after the door lock operates, potentially due to a fault, connection or wiring issue associated with the door lock feed to the PCB and rest of the machine.
- What fixed it
- Do not assume the PCB is faulty and replace it speculatively. The accepted advice was that PCB replacement would be a gamble. Further diagnosis should focus on the door lock circuit, its connections and related wiring supplying the PCB and machine functions. The exact repair was not confirmed.
- Checks to try
- Pump checked and found not blocked
- Pump checked and found not open circuit
- Door lock activates
Safety: Further diagnosis should be carried out by a suitably qualified appliance engineer.

Hello Tom. It could be, but it would be a big gamble to change it. The fact that the door locks shows there is a live and neutral to the washing machine. But the circuit is stopping somewhere. When the door lock activates it should do two things, it activates the lock, and passes power to the pcb and rest of the machine. So potentially the lack of power could be because of a fault, or connection, wiring issue related to the door lock. It's unusual though.

Having said that, another topic here highlights a similar fault on a Beko washing machine that turned out to be just a faulty diode. Check it out, however, you really need to know what you are doing when examining the PCB. Even washing machine repairmen don't normally mess with them and none of the parts are available as spares so equivalents have to be sought
