How to heat water -truma C EH603 A

[Merdymort]

Hi all (again ) just trying to figure it all out still here. Got a rapido 7063f, 2006 with the above truma water heater. As far as I can see from the internal dials this should work on electric. I am just in the process of cleaning the water system, the puriclean is in the tank, the cold water runs fine out of all taps/shower and now I just want to make sure it’s run through hot water boiler and those pipes too.
I have plugged van in, turned dial inside to hot water but there’s no water coming out of the taps when switched to hot, even after waiting 30 mins. Help please, what have I missed?
There is a red switch at the side under a sliding cover… doesn’t seem to have an off or on tho???

Also, assuming I get it all working, when I want to empty it all out of the water system do I need to use the frost dump valve to ensure none left in boiler or is it enough to just run the water out?

I think the red switch may be a 240v isolator for your boiler. If you see behind it to see if it is fed by 240v cable. If not just try it and see if the water heater works.

Your boiler settings are for water heating to 40 degrees, and only using a single element. I think I can see the orange light glowing which indicates it getting 240v.

Are you getting no water, or no HOT water? You will need the pump on and to have bled the air out the system before it can get into the boiler to heat.

It’s also quite likely the electric element doesn’t work, like one of mine, and it’s normal that it’s the first (single) element to fail first. So you may have more luck selecting twin element heating, or use your gas.

Thanks. I did manage to get it to work and did one rinse last night. Have noticed this morning though that I can’t make the boiler dump valve stay closed. There’s a red button under a slider, thought that might be a reset but pressing it doesn’t change anything. How can I make the valve stay closed please, any ideas?

You need to press button and turn top at the same time

Theoretically if those are the dials you have should the van be able to be heated on 240v?

Yes.
Top dial to bottom setting for heat and hot water, or one above for just heating, and then bottom dial set to fully up for two element electric power, or next one down for single electric power. Single electric power is terrible for heating a van though as not enough power. Twin electric power is brilliant to be honest.

Will try again

That final sentence should read
“Twin electric isn’t brilliant to be honest”.
Sorry

I just use gas. Best results from that.
