Hi everyone
On site got up no 240 power. Rcd had tripped in van.. I was on an old supply fir main feed so whether that went which triggered rcd?? Or rcd triggered main feed.. so moved pitch to new feed with accessible rcd! However, now my heating or water won't wrk on electricity fine on gas. I'm wondering if fuses gone on the boiler??
Any advice would be appreciated

If the RCD in the van Tripped it will be equipment in the van that has Tripped it.
As the heater is not working probably a problem with one of the elements.

If it is one of the Truma elements they are expensive to replace, probably not worth the bother. Boiler works better on gas an gas is cheaper than electricity.

This happened to me a few years ago, the fridge 24ov element had burnt out. Replacement of the element fixed it, for info the fuse didn't blow.

What Lenny HB said. The error code on the Truma control panel might give you a clue, though tbh they are often indecipherable. Are your other 240v items working (fridge, power sockets)?

Presume you mean 2 knobs - so a different means of turning off/on than mine. There are some youtube videos that help find the fuses on a Truma - but it really depends how technically-skilled you are. Lenny HB has probably the best advice

Does the orange light on the bottom knob illuminate on EHU if there dial is set to 1 or 2 wriggly worms with the top knob set to either heat or water (or both)? If it does it usually means one of the elements has failed.
You can get codes from flashing lights in the heater PCB but that's getting pretty technical and rarely of any use to us lay people.

Just realised RCD tripping so very likely faulty element shorting to boiler casing rather than internally. Is RCD ok if 240v turned off on boiler?

For info.
My boiler (same as yours) blew the trip, and it was one of my electric elements in the boiler. Boiler showed no signs of the problem and still doesn’t now. All lights and controls working it just doesn’t heat properly.
So if your elements have failed it probably won’t put error code code up, it just won’t do what it should.

I just use gas as it works better on that anyway and with refillable isn’t costly. Unlike the cost of element replacement.

Oh yes someone else said with refillable it's cheaper.. element's cost abt £200 pounds ibelieve?

I got a pair off ebay for £145 about 12 months ago and fitted them myself. You can pay much nearer to £300 for original Truma ones but I can't see how they can be any better than the ebay ones. I was lucky that I could access the elements without pulling the van apart which is not usually the case unfortunately.
