8.6.3 Extraordinary
maintenance (water level limits substitution)
 
 
To replace the water level limits or parts of it, follow strictly the instructions below: 
1. Ensure that the new ceramic plug is intact 
2. Check the length of the rod 
3. Ensure that the rod is coaxial to the plug axis 
4. Inspect the electrical system and, in particular, ensure that the resistance of the electric circuit linking 
the ceramic plug to the electrical panel is intact (resistance must be over 10 MOhm)
5. Ensure that the automatic level control consisting of the two ceramic plugs and their conductivity-relays,
work well
 
 
 
8.7 TROUBLESHOOTING
FAULT
POSSIBLE CAUSE
RECOMMENDED REMEDY
Interrupted water level monitoring
Scaled stainless steel bar 
Broken connection cable 
Faulty safety level relay
Temporary replace the safety electronic 
relay with one of the two relays in the 
panel. 
If this is the problem, replace definitively 
the faulty relay. 
Safety intervention level 1 or 2
Water does not load
See “Loading” inconv.
Blocked pump
See. “Blocked pump” inconv.
Dirty pump sucking filter
Clean the filter
Level regulation anomaly
Temporary replace the safety electronic 
relay with one of the two relays in the 
panel. 
If this is the problem, replace definitively 
the faulty relay. 
Level regulation probes short circuit
Dismantle the adjustment probes to 
inspect visually the ceramic insulation 
Insufficient head (=different height 
between the collecting vessel and the 
pump levels) in comparison with water 
temperature 
Clean the pump sucking filter 
Pump cavitatation
Decrease the pipe resistance between the 
collecting vessel and the pump by 
increasing the passage section 
Insufficient water load
Pump sense of rotation
Invert one of the two phases (three-phase 
pump) 
Incorrect electrical panel connection
Consult the electric diagram
Faulty level safety relays
See “Safety intervention level 1 or 2” 
Check the pressure switches regulation 
Burner always on 
 
Regulation pressure and/or safety switches 
OFF 
Check the pressure switches connection 
to the electrical panel 
Burner problems
See burner manual
Interrupted burner fuses
Replace fuses
Lack of burner consent from the regulation 
pressure switch 
Replace regulation pressure switch
Lack of burner consent from the level safety 
relays 
See “Safety intervention level 1 or 2”
Burner always off
Incorrect electrical panel connection
Consult the electric diagram
