6. Troubleshooting
Sympton Solution
Appliance not heating Neon indicator light is not illuminated, check the thermal
cut-out and reset if necessary.
Neon indicator illuminated but not heating – check the
heating element and replace if necessary.
Water too hot Adjust the thermostat setting down (counter clockwise),
if it does not respond then change the thermostat.
Water too cold Adjust the thermostat setting up (clockwise), if it does
not respond then change the thermostat.
Pressure relief valve If the pressure relief valve discharges only during the
discharging heating cycle, this is a sign of a lack of pipework to
accommodate expansion. Check the incoming pipework
for non-return devices and remove if safe to do so
(see diagrams A-D).
If the pressure relief valve is discharging permanently,
this is likely to be a result of the incoming water pressure
exceeding 6 bar. A pressure reducing device should be
fitted to reduce the incoming water pressure.
