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?

Are both valves opened when you fill it?
