Truma Water Heater Problems

Truma water heaters are a popular choice among caravan owners, offering both gas and electric heating options. But, like any piece of equipment, they’re not without their issues. A common problem reported by users is the Truma water heater working fine on gas but not on electric. Let’s delve into the root of this issue and explore potential solutions.

1. Fuse Checks:

One of the primary steps when troubleshooting electric issues is to check the fuses. Ensure that all the fuses related to the water heater are intact.

Possible Solutions:

• Carefully inspect all fuses for any visible damage.
• Ensure that they are all in the correct position, especially if your model has MCB switches. Remember, in some models, the switch should be UP for the device to be on.

2. Model Specifics:

Different models of Truma water heaters might have slight variations in their setups and controls.

Possible Solutions:

• Refer to your specific model’s manual. For example, if you have the Avante version of the 534L, there might be a cartridge fuse in the on/off switch for the boiler that could be causing the problem.
• Ensure other appliances that share a power source with the water heater, like the fridge or mains spotlights, are functioning correctly.

3. Heating Element Concerns:

The heating element, like in many other appliances, can sometimes fail or malfunction, leading to the electric heating not working.

Possible Solutions:

• If other troubleshooting steps don’t resolve the issue, the heating element might need to be inspected or replaced.
• Before replacing the entire unit, it might be wise to seek a diagnosis from a Truma main dealer as opposed to a general caravan dealer, as the latter might lean towards suggesting a whole new unit.

4. Reset Mechanism:

Truma boilers do come equipped with an over-temperature reset switch. Unlike some other brands, Truma’s reset mechanism is self-resetting, and understanding its function is vital.

Possible Solutions:

• If you suspect the reset switch has been triggered, disconnect the mains supply or switch off the electric heater.
• Allow several minutes for the reset switch to cool down, during which it will automatically reset itself. This mechanism is known as a ‘Self Hold’ reset.
• A common reason for this switch tripping is leaving the unit on during transportation or setup. Ensure the boiler is filled before connecting to an electric supply to prevent overheating and subsequent tripping.

5. Gas as a Temporary Solution:

If you find yourself with a non-functional electric heating system while on the move, using the gas option can sometimes help reset the electric heater.

Possible Solution:

• Switch the water heater to gas mode. After some time, revert to the electric mode to check if the issue has been resolved.

Conclusion:

While the Truma water heater is a reliable appliance, understanding its quirks and features is key to effective troubleshooting. If problems persist, always consider consulting with a professional or the manufacturer. Remember, safety first; always ensure the unit is off and properly cooled before attempting any repairs or checks.
