What it is
The Sime main PCB with wiring is the control board at the centre of the boiler's electrical system. It takes demand from the room thermostat, programmer or hot water sensor and sequences the fan, pump, ignition and gas valve through each heating and hot water cycle. This board is supplied with its wiring harness, under part number 6230665, for Sime gas boilers.
Because the board carries the boiler's operating logic, a failure here usually stops the appliance working altogether rather than causing a minor drop in performance. Replacement is a straight board swap once the correct part number has been confirmed against the unit being repaired.
Signs this part needs replacing
- Boiler has no display and will not power up
- Repeated lockouts or fault codes that clear and then return
- Fan, pump or ignition sequence does not start on a call for heat
- Heating or hot water runs intermittently and cuts out mid-cycle
- Visible scorching, burn marks or a blown fuse on the board
Before you order
- Match the part number printed on the existing board to 6230665
- Check the alternative number 2043152 if the old board carries that reference
- Note the boiler model and serial number from the data plate
- Inspect the wiring harness plugs and pins for heat damage before refitting
