Troubleshooting
Symptom
Likely cause
Action/Remedy
System does not operate fully
(reduced or no water flow):
Hot or cold water supply isolation valve
closed
Check and open valve
Debris has caused blockage in thermo-
static mixer, or group mixer
Isolate mixer and service strainers and
cartridge see mixer instructions to service
Pressure difference between hot and
cold supplies is too high
Adjust screws on mixer to balance. Or fit
pressure reducer on high pressure supply
Water flows from shower head
but no air:
Fan is not running
if so check seal of air hose connections
and that hose is kink free
Power is not being supplied
If no check electricity supply
Conduct hard reset by switching off
electrical supply and waiting 10 seconds
before turning on
Debris in fan
Clear any debris from fan and follow Fan
Test Function p.12
If fan runs then check flow sensor is not
jammed or faulty
Temperature fluctuating:
Thermostatic control/Boiler issue
Check thermostatic mixer valve/boiler for
an issue, call a specialist if necessary
Poor/no water flow:
Blocked water filter/strainer
Isolate water supply and service strainers
in mixer or group mixer
Water flow too strong:
Flow restrictor not installed
Check if the flow restrictor is properly
installed (in Solenoid flow)
Water flow continuing after fan
has stopped:
Debris or limescale build up in Solenoid
valve
Check Solenoid and replace if necessary
Inconsistent water flow:
Debris or limescale build up in Solenoid
valve
Check Solenoid and replace if necessary
