TROUBLE SHOOTING (GAS SAFE ENGINEER ONLY)
18
Reset control by pressing start button for 1 second and releasing. Then press again the same way
to attempt a normal start command. Repeat up to 10 times as necessary to see if this overcomes
the issue as it may resolve itself eventually.
Check to see if gas is present at gas appliance inlet. (Check gas supply is on, the gas line purged of
air and the supply pipework is free of blockages or contamination) Rectify and perform start
cycle to clear the Error code.
Try to light the fire as normal. No gas on appliance
inlet
Clean the pilot free of any dirt, dust carbon granules or lint, especially around the brass body of the
bunsen burner and its gas and electrical connection and the area around the flame ports and the
spark plug and electrode tip. Check the electrode gap is 3- 4 mm. Rectify and perform start cycle
to clear the Error code. Try to
light the fire as normal.
Replace pilot if necessary Pilot contaminated with
lint or other materials
Check ignition cable for damage and listen and watch for tracking out of spark to see if it is present
but not making it to the electrode tip on the pilot burner. If cable damaged, replace
cable. Reset error by
performing a normal start
cycle and try to start again.
Replace pilot if necessary.

Reset and try again Check switch for damage, contamination across terminals or damaged wiring. Disconnect wired
thermostat if fitted and try a start, if it works replace thermostat E13 Wired thermostat is
out of tolerance Check wiring and
thermostat
Reset and try again Clean as necessary. Replace switch panel as necessary if damaged or too contaminated.
disconnect wired control panel and try again – if it works replace wired control panel E14 Button (-) sticks
either on TESC or on
wired control panel (if
used) Check for contamination
around buttons
Reset and try again Clean as necessary. Replace switch panel as necessary if damaged or too contaminated.
disconnect wired control panel and try again – if it works replace wired control panel E15 Button (+) is shorted
to other buttons
either on TESC or on
wired control panel (if
used) Check for contamination/
damage
Reset and try again Clean as necessary. Replace switch panel as necessary if damaged or too contaminated.
disconnect wired control panel and try again – if it works replace wired control panel E16 Button (ON/OFF) is
shorted to other
buttons either on
TESC or on wired
control panel (if used) Check for contamination
/ damage and replace
wired switch panel if
necessary
Reset and try again Jumpers on back of
valve missing Check to see if jumpers
are in 10 way connector
Reset and try again Check and clean around the area of the pilot for lint and other contamination. Check where the
thermocouple connects to the TESC control for the same contamination. Clean these areas. E05 False flame signal Flame sensing on pilot
