A Rimor that doesn't produce hot water on 230V while the heating works often has a faulty heating element in the boiler.

A Rimor that doesn't produce hot water on 230V while the heating works often has a faulty heating element in the boiler. With gas operation, it usually points to a dirty burner or a tripped gas safety valve. Also check that the boiler isn't accidentally empty or the frost protection valve isn't closed.
The exact cause depends on the type of boiler and the energy source used. A systematic check of gas, 230V and water pressure usually quickly reveals the problem.
Rimor has been building campers with proven hot water systems for years. In most models you will find a Truma Combi (combi boiler for heating and hot water) or a Truma boiler (separate boiler tank). In the more expensive A-class and semi-integrated models, an Alde system is often used, which runs on gas, 230V and sometimes engine heat. Each system has its own typical quirks.
First check which source you are using and then proceed in a targeted manner:
For a full step-by-step guide, see our general explanation of a camper boiler without hot water. There you can read how to systematically check gas, electrics and water pressure.
Always start with the simplest checks: is the boiler on, is there water pressure (at least 1 bar), is a fault light on? With Truma systems, a red LED often blinks a specific fault code. Replacing an ignition electrode typically costs 50 to 120 euros, a heating element 80 to 150 euros, and a safety valve 20 to 40 euros, excluding labour. With an Alde system, a new burner or circuit board can easily exceed 300 euros. If in doubt, have a camper technician with Rimor experience look at it, because improper work on gas or 230V is dangerous.
If the boiler is older than ten years and several faults occur at the same time, a complete replacement (new Truma Combi unit) can cost up to 2,500 euros or more. In that case, it is wise to weigh the market value of your motorhome against the repair costs.
