Replace boiler control unit.
Possible cause
Check / solution
Check:
• The sealing of the viewing glass;
• Whether front plate of heat exchanger is properly tightened
• Front plate sealing;
• Whether ignition electrode is properly fitted
Check wiring between heat exchanger fuse.
Check the minimum water pressure, read off the gauge and check
for leaks.
Check that the pump is working; turn the spindle with a screwdriver,
if that works but the pump still does not respond, check the wiring;
that is in order the pump is faulty.

Control stop or lock-out
The code K8 , K5 or K9 can appear in the display.
• Code K8 is a control stop and will appear if the measured
flow temperature (t1) is higher than the flow temperature
set (Tset flow). The boiler will start working again automatically once the flow temperature falls below the flow temperature
set.
• Code K5 is a control stop from 3 till 10 minutes and
appears if the set flow temperature (t1) has already been
reached and the heating demand still exists.
• Code K9 is a shut down and appears if the maximum
temperature rise is exceeded or if the ΔT between the supply and return temperature ≥ 45°C or a rate of rise in the
flow temperature > 1°C/sec. And also at a boiler-start with
no through flow or insufficient water. The boiler will try to
restart after 10 minutes.
• Code K9 is a shut down and can appear in the following
situation:
- The lock-out down input (between connectors 5 and 6 on
terminal block X9) has been activated (= opened).

The shut down will disappear once the cause has been
removed!
