CLAGE water heaters repair
Book a technicianCLAGE instantaneous water heater repair and hot-water checks
Inspection distinguishes low water flow, insufficient temperature and complete loss of heating. Tell us if the problem followed work on the water supply: air in the circuit and restarting must be addressed according to the model instructions. Do not open the casing or experiment with operation to diagnose the fault yourself.
Checks may cover the water path, filters, sensors, controls and heating assembly, depending on the configuration and complaint. A display message needs the exact model for interpretation from its manual; codes do not necessarily mean the same thing across heaters. Once the cause is identified, the repair and any part are quoted before work.

Symptoms and inspection notes2
Water colder than usual
Record the setting, whether one or more outlets are affected and whether usage changed.
Heater stops or displays a warning
Record the full message and model. Do not repeatedly retry or bypass protection when the warning persists.
DCX-specific indicator example1
This CLAGE support example concerns DCX. Record the model and flashing pattern accurately; do not apply it to every heater.
| Code | Meaning | Cause |
|---|---|---|
| DCX: All LEDs flashing | All LEDs flashing: electrical connection and supply voltage need checking | Have a qualified electrician inspect it; do not open the heater or alter breaker ratings yourself. |
Care according to your manual1
Prepare appliance details
Keep the manual, model and problem timing available; leave electrical, gas and internal work to a qualified professional.
A question about the problem1
Does every CLAGE heater use the same flashing indicator pattern?
CLAGE states that all LEDs flashing on DCX requires checking the electrical connection and supply voltage. This is specific to DCX; do not open the casing or change the breaker yourself. Send the model and warning description.
