13.3 Fault table
LED diagnostic
traffic light Fault Cause Remedy
No display No hot water. The fuse/MCB in the fuse box has blown/responded. Check the fuses/MCBs in your fuse box/distribution
panel.
The safety pressure limiter has responded. Remove the cause of the fault (e.g. faulty pressure
washer).
Protect the heating system against overheating by
opening a draw-off valve downstream of the appli-
ance for one minute. This depressurises and cools
down the heating system.
Activate the safety pressure limiter at flow pressure
by pressing the reset button; see also chapter "Com-
missioning / Initial start-up".
The PCB is faulty. Check the PCB, replace if required.
Flashing green
light
The appliance does not start. Inadequate flow rate. Descale / clean the connected aerator / shower
head.
Inadequate flow rate. Clean the strainer in the water inlet.
No hot water at flow rate
> 3 l/min.
The flow sensor (DFE) plug has not been inserted. Plug the flow sensor plug back in.
The flow sensor (DFE) is faulty. Check the flow sensor and replace if required.
Flashing green
light and steady
yellow light
No hot water at flow rate
> 3 l/min.
The high limit safety cut-out has responded or its
lead is broken.
Check the appliance and the high limit safety cut-
out.
The set temperature is not
achieved.
One phase down. Check the fuses/MCBs in your fuse box/distribution
panel.
The heating system is faulty. Measure the resistance of the heating system and
replace if required.
The outlet temperature sensor is faulty. Check the outlet temperature sensor and replace if
required.
The appliance is at its output limit. Reduce the flow rate or install the flow limiter.
The outlet temperature is approx.
45 °C, irrespective of the set value
transducer
The set value transducer or connecting cable is faulty,
or the connecting cable is not attached.
Attach the connecting cable; replace the set value
transducer if required.
A set temperature of > 43 °C is not
achieved.
The temperature limit (childproofing) / anti-scalding
protection is enabled.
Disable the temperature limit (childproofing) / an-
ti-scalding protection.
Flashing green
light and steady
red light
No hot water. The outlet temperature sensor is faulty. Check the outlet temperature sensor and replace if
required.
The cold water sensor is faulty. Check the PCB, replace if required.
The air sensor detects the presence of air in the water
and briefly interrupts the heating output.
The appliance restarts after one minute.
The flow rate is > 25 l/min. Reduce the flow rate or install the flow limiter.
Selected temperatures above 45 °C
are not achieved.
The cold water inlet temperature is above 45 °C (e.g.
in the case of water preheated by solar energy).
Reduce the cold water inlet temperature to the ap-
pliance.
