Cause
partially closed stop or service valve in
water supply pipework to the mixer valve.
instantaneous water heater cycles on and
off as the flow rate or pressure is too low.
Head of water is below the minimum required
inlet filter is partially blocked.
Hot or cold water being drawn off
elsewhere causing pressure changes
or instantaneous boiler changes.
imbalanced inlet pressures.
airblock or partial blockage of the pipework.
no hot or cold water reaching
the shower valve.
this is normal for a short time
after turning off.
Shower flow control valve failing to close
fully, possibly due to water borne debris.

necessary to vary draining time.
Remove flow control valve
assembly and check.
Check condition of flow control valve
and replace as necessary.
Reset maximum water temperature.
Check inlet filters for any blockages
and clean as necessary.
Refer to important information section.
adjust hot water temperature or wait for
