8 Troubleshooting

8.1

Error messages

Resetting the control panel allows the appliance to be restarted.
The message

appears when a fault code is detected. After resolving

the problem, pressing the

key resets the appliance's functions and

thus eradicates the fault.
If several faults occur, they are displayed one after the other.

1. Reset the control panel by pressing the

key for 3 seconds,

when an error message is displayed.

In economy mode, the appliance will not run a domestic hot water

heating cycle after a central heating cycle.

2. Display the current operating status by briefly pressing the

key.

8.1.1

EHC–05 error codes

An error code is a temporary status, resulting from the detection of a heat

pump anomaly. The control panel attempts automatic restart of the heat

pump until it switches on.
When one of the following codes is displayed and the heat pump cannot

restart automatically, contact a maintenance technician.
