Low pressure light

I get the low pressure light on low power but on high power it flicks between working and showing the low pressure light.



I have checked the stopcock (only valve upstream), gauze filter, stabiliser valve (flow varies from cold to hot) and the flow valve is pushing the microswitch fine (in fact it nudges the whole PCB). The relays spark frequently (lower one in low power, both in high power). Are there any other tests I can or need to do, or have I done enough to eliminate everything except the power PCB?



The price of a power PCB is close to a new shower, especially as this one is on a 32A MCB so I can only use it on low to avoid tripping (no 40A way spare until I change the consumer unit) - seriously thinking about replacing it with a 7.5kW shower for now if it is the PCB.

It certainly sounds like a PCB fault and you are correct without changing the fuse you are stuck with 7.5kw
