10. Disturbances in comfort
Troubleshooting
Note! The FIL-SPL boiler might have an external control voltage that the main switch does not turn off.
Basic actions
Note! After power cut there is two hours time delay before full power is taken into use.
Note! The dry-boiling preventer (models from 120 kW to 1600 kW), temperature limiter or overload will trip
the main switch.
Note! After the main switch has tripped, ensure that the main switch is reset by first positioning the switch
to “0” (off) and then back to “I” (on) position.

Check for possible power cut

Check each main fuse of the property

Check each supply fuse of the FIL-SPL boiler

Check internal fuses, note that only qualified electricians are permitted to service internal boiler
parts and open the cover

Check if the dry-boiling preventer has triggered (models from 120 kW to 1600 kW). If the dry-
boiling preventer is triggered, the indicator light “HÄLYTYS” will lit as red and indicator light
“TOIMINTA” will be off

Reset the dry-boiling preventer by pressing “VIRITYS” button, the indicator light
“TOIMINTA” will lit as green and indicator light “HÄLYTYS” will be off

If resetting is not operating, ensure that there is water in the system

If both indicator lights “HÄLYTYS” and “TOIMINTA” are off and the device has power, check
the 50 mA fuse of the dry-boiling preventer. Replace only with 5 x 20 mm class tube fuse of
type “50 mA T” that meets IEC127 standard

If replacing the fuse does not solve the issue, there is a system malfunction in the dry-
boiling preventer. Use only original spare part as a replacement

Reset the main switch according to instructions below

Check if the temperature limiter has triggered

Check that the circulation pumps are operating accordingly

Reset the temperature limiter by pressing the button

Reset the main switch according to instructions below

If the temperature limiter trigs again (after cooling down), the limiter may be damaged.
Use only original spare part as a replacement

Check if the main switch has tripped. To reset the main switch, first position the switch to “0” (off)
and then back to “I” (on) position

If the main switch trips again, re-check dry-boiling preventer and temperature limiter

If the dry-boiling preventer (models from 120 kW to 1600 kW) and temperature limiter are
operating accordingly, the main switch may be damaged. Use only original spare part as a
replacement

Check pressure of the system and possible leaks

If the control unit is damaged, the FIL-SPL boiler can be used in backup mode, more information is
available on Backup mode.
