Self Diagnostic Error Codes
The temperature indicator also serves as an error code indi-
cator. Should an error occur the status LED (which is nor-
mally green) will flash red. This will be accompanied by the
temperature indicator flashing an error code of 01 - 08.
Check code and proceed as follows:
01: Failure to ignite (see 6.6.5). To re-set turn mode selec-
tor switch to re-set position for approximately 10 seconds,
then back to original position.
02: Overheat - Normally associated with either poor or lack
of primary water circulation. Wait for appliance to cool then
re-set as described for code 01.
03: Problem with fan/flue. Re-set as described for code 01.
04: Insufficient water pressure or poor flow in system.
Alternatively, problem in the condensate drain trap.
This is a temporary alarm, and does not need to be reset
manually, as the alarm will be reset automatically when nor-
mal operating conditions resume.
05: Re-set as described for code 01.
06: Hot water thermistor open circuit.
07: Primary thermistor open circuit.
08: Re-set as described for code 01.
IMPORTANT:
The lock of Primary Store Safety Thermostat interrupts the
boiler's supply circuit (status LED off, temperature indicator
off).
Before releasing the thermostat, wait for appliance to cool
sufficently (approximately 15 min) and then:
- turn off the mains electricity supply
- remove top casing (see fig. 52)
- pull off the plug (see fig. 52a)
- reset the Primary Safety Thermostat pushing the button
- reassemble in reverse order.
Should the appliances continue to lock out call service
engineer.

FAULT FINDING GUIDES

On the following pages are the fault finding guides. Be sure
to read the notes below before begining any fault finding.
NOTES:
1. To ensure correct fault diagnosis it is important that these
guides are carried out in the set order.

2. Check the electrical supply polarity is correct before
carrying out fault finding (lockout will occur if the polarity is
reversed).
3. To ensure that internal/external controls (if fitted) do not
interfere with fault finding, disconnect the wires from termi-
nals 2 & 3 (labelling them in the process to ensure correct
reconnection) and provide a solid link between 2 & 3.
