Boiler pressure sensor
My son's Glow-worm 30cxi condensing combi has performed perfectly for 3
years. Today, it didn't fire up. The display was flashing a pressure of 0.4bar, so he opened the filling valve. He heard some water flow in, but the pressure barely changed, and the flow soon stopped. Power cycled, and it showed 0.6 bar, and fired, but still wouldn't accept any more filling. Let a bit of water out through the prv - no change of reading, but it would then admit a small amount to refill. It sounds like a faulty pressure sensor to me, but I suppose it could be a circuit board fault. Can the pressure sensor be tested other than by substitution? Can any dummy load be applied to the circuit board to give a nominal pressure reading? Pressure sensors seem to be around the £70 mark, so he'd rather not buy one if the fault's more likely to be elsewhere. Glow-worm part 2000801911, GC E83997. Any ideas, please? -- Kevin Poole ****Use current date to reply (e.g. )**** |
