2.24 - Failures display
The boiler has many selectable options. Please ensure the correct selections are made for the type of
installation you have made. If you have selected the use of a room thermostat, or hot water cylinder, the
boiler will not operate until these devices are connected.
The boiler indicates a boiler fault by flashing all segments of the temperature display.
In case of boiler's temperature failure, all 14 LEDs
in front of symbol "°C" are blinking. The boiler is
off, the water pump still running.
In case of Domestic Hot Water sensor failure (if parameter
= 1), all 14 LEDs in front of symbol
"°C" are blinking. The boiler is automatically restricted to heating.
In case of outside temperature sensor failure (if parameter
= 1 or if used to automatic operation -see
§ 2.20-), all 14 LEDS
in front of "°C" are blinking. The boiler is restricted to heating.
Please call the Dimplex Customer Service department -see Servicing section-
2 FLASHING SEGMENTS in front of bar -indicate the system pressure has fallen below the minimum
operating pressure.
• Check if water has discharged from the pressure relief valve. If so call a Dimplex service agent.
• Check for leakage in the system.
Once the fault has been cleared the boiler will turn on again if the system is filled and pressurised to over
0.5 bar.
