13.3 Condensate Sensor
Refer to fault finding chart.
The boiler is fitted with a safety device to prevent the boiler from
working if the condensate drain pipe gets blocked.
Remove the condensate drain cap, diagram 14.2.
If condensate is backing up to the sensor position, the drain is
blocked and it must be cleared before the boiler will work.
Inspect external condensate drain pipe and clear away any
debris or ice. Release ice blockage by using warm cloths on the
pipe.

12.5 Condensate Drain
Remove the cap at the base of the condensate drain trap, see
diagram 12.8 and carefully flush through, from the condensate
collecting tray, diagram 12.6, taking care not to allow any water
to overflow the tray.
When refitting the cap make sure a water tight seal is made.
12.6 Operational Checks
After completing a service, before fitting the casing, check the
inner case seal to ensure that it is in good condition, renew if
necessary.
13.1 Electrical
Important. On completion of the Service/Fault Finding task
which has required the breaking and remaking of the electrical
connections the earth continuity, polarity, short circuit and
resistance to earth checks must be repeated using a suitable
multimeter.
Refer to Fault Finding, Wiring diagram 13.2 and Functional
Flow diagram 13.3.
Note. Failure of an indicator light does not warrant the
replacement of an otherwise satisfactory part.
13.2 Electrical Supply Failure
Failure of the electrical supply will cause the burner to go out.
Operation will normally resume on restoration of the electrical
supply. If the boiler does not relight after an electrical supply
failure the overheat device may need resetting.
To reset, press the reset button on the underside of the boiler,
see diagram 13.4.
If the cutoff operates at any other time press the reset button and
the burner should relight. If the fault persists refer to Fault
Finding Chart.
There is a further cutoff mounted on the flue hood, see diagram
13.5 which also may need resetting.
