Checking an Immersion Heater last week ... tripping RCD after board change .... poor readings to earth ... I'm thinking I don't mess with these any more , get a plumber .  Then ...I'll just double check with wiring disconnected although its a DP switch .     

Element readings are now fine .......  at the switch on the landing ..what I saw as the earth wire at the heater end was PME'd into the neutral at the switch  and no incoming earth feeding the switch . :C

The old story ....never assume anything in this game.

So back to rewire it .
