“S.” briefly appears.

4.8 Troubleshooting

In the unlikely event that a problem occurs with the oper-

ation of the ecoTEC boiler, the following points should be

checked:

Boiler fails to operate:

– Is the gas supply turned on (see 4.3.1)?

– Is the water supply turned on (ecoTEC combination

boilers only, see 4.3.1)?

– Is there enough water in the heating system (see 4.3.2)?

– Is the electrical supply switched ON?

– Is the main ON/OFF control in the “ON” position

(switch position “I”, see 4.4)?

– Is there an ignition problem (see 4.8.2)?

Hot water operates but no central heating (ecoTEC

combination boilers only)

- Is the heating turned ON (see 4.6.1)?

- Are all external heating controls ON (see 4.6.3)?

Caution

Inappropriate modifications can cause damage.

If your boiler still does not operate then please

consult your installer or Vaillant Service Solu-

tions (0870 6060 777).

4.8.1 Problems due to low system water pressure

The device switches to “Fault” if the water pressure in

the heating system is too low. This malfunction is indi-

cated by the fault code “F.22” (dry fire) or “F.23” or

“F.24” (lack of water).

You can only start up the appliance again when the

heating system is sufficiently filled with water.

4.8.2 Ignition problems

If the burner fails to ignite after five attempts, the de-

vice does not start up and switches to “Fault”. This is in-

dicated by the fault code “F.28” or “F.29” in the display.

On ecoTEC plus appliances the display also shows the

flame symbol with a cross through it (1). On ecoTEC pro

appliances, the red LED (2) also lights up.

Automatic ignition can only take place after you manu-

ally reset the fault.

• To reset the fault, press the reset button (3) and hold

it down for one second.

Caution

If the boiler still shuts off after three attempts

of resetting, please consult your installer or

Vaillant Service Solutions.

4.8.3 Flue problems

The appliances are fitted with a fan. If the fan does not

work properly, the appliance will switch itself off.

The display shows the symbols

and and the fault

message “F.32”.

Note

If contacting Vaillant Service Solutions please

remember to quote the fault code, as this will

help to pinpoint the fault.
