Self Help Check List
a) Water too HOT Press the cooler button when in NORMAL operation.
Clean spray plate holes.
b) Water too COLD Press the warmer button when in NORMAL operation.
c) Spray pattern poor Clean spray plate. Select outer / inner only.
d) Display behaves erratically Switch off electricity at ceiling / isolating switch, wait a few
seconds, switch on again. (Note the shower should be
switched off each time after use at the ceiling switch).
e) Water does not flow when Start / Stop Note: It there is no water flowing then the shower will
button is pressed automatically switch off after 30 seconds
lights on Check the water supply is turned on.
“o” and then “t” flashing in display Unit in over temperature mode see section on “purging”
no lights Check ceiling switch is on. Check power is on.
f) Warmer / cooler buttons do not Unit in “temp lock” mode. See relevant section on how to
function override.
g) Unit makes a whirring noise, This is normal. There is a motor inside the shower used to
especially at the start of the adjust the flow and this always operates at the start of
shower session each shower.
Professional Service Check List
This additional checklist is provided for the benefit of the qualified service representative.
Warning. Switch Off The Electricity At The Isolating Switch Before Removing The Front Cover To Make
Checks.
a) Poor temperature control Check inlet / outlet thermistors to see if they are in circuit.
Check for blockage in filter of solenoid valve.
Check board configuration for correct power rating.
b) Water too COLD Check circuit through thermal cut-out.
Check circuit through all 4 elements. Test should be done
using a low voltage resistance meter whilst the power is
switched off at the isolating switch.
Check circuit through triacs.
Check working voltage.
c) Poor or no control over water flow Replace inlet flow valve assembly.
d) No water when start button is pressed Check water supply. Check circuit through solenoid coil. If ok
replace logic PCB.
e) Unit has been switched off using stop Replace triac PCB.
button but can be heard heating the
water.
f) Pressure relief valve blown Check for cause of high pressure and remove it.
Replace pressure relief valve.
g) Temperature buttons do not function Unit is in templock mode. Remove cover and change position
of templock switch to OFF (see Fig. 15 for location) or explain
feature to user.
h) Shower runs cold for about 30 seconds Flow transducer fault. Check that internal blade "spins" when
and then switches off by itself the water flows. If not, replace.
