REMEDY
4. Release 'LOW' and 'START/STOP' buttons.
5. Press 'START/STOP', the shower will be reset to
previous settings.
A. Ensure that the shower is on 'HIGH' setting, where
applicable.
B. Reduce the flow by turning the water control knob
clockwise slowly. NOTE: If the knob is turned too far
clockwise, the safety pressure switch inside the shower
will turn off the heating elements. This is apparent
when the 'reduce temp' light starts flashing. If this
happens, turn the knob anticlockwise until the light
stops flashing.
A. Increase the flow by turning the water control knob
anticlockwise slowly.
B. Clean the handset sprayplate.
C. Switch to 'LOW' setting, if applicable.
A. Clean out the sprayplate as in 'Maintenance' Section 8.
Call a service engineer to remove the front cover and
reset the PRD by removing the bent bracket, pushing
the black outlet boss back into the heat exchanger, and
refitting a new bracket.
If the fault occurs again without the hose being
damaged or the handset blocked, contact our Service
Department.
B. Replace kinked or damaged hose and be careful not to
turn water control knob too far anticlockwise. Reset as
in 'A'.
A. Increase the flow by turning the water control knob
anticlockwise. Clean the handset and sprayplate.
B. Ensure that your stop cock and servicing valve are fully
open. If they are, ask your installer or the local water
company to check that the running pressure is above
the minimum required (see 3.2).
