1. Check the water supply.
Water pressure - It must be between 1 & 6 bar and kept as constant as possible.
If not, a water regulator valve must be installed on the supply line and adjusted at 2 bar. Also check the
condition of the inlet valve, the electrical connection and the state of the F2 fuse (2AT). If out of service
replace valve and fuse.
2.
The blue hose into the filling cup is incorrectly positioned or folded.
The blue hose must have one end
in the water feed hole and the other in the middle hole. If the hose is folded, please change it.
3. Check that the condensate is drained properly.
Condensate has to be evacuated otherwise it will cause
water spitting by creating a pressure rise into the tank.
4. Check the proper closing of the purge valve.
A piece of limestone keeps the valve open. Also check with
an AK-Muller drain valve (white coil), the resistance R26 or RC3 has been removed.
5. Water level detector.
Check that the level sensor, detector and the pressure balancing hose are clean and
that nothing prevents the water from circulating. Also check the electrical connections between the level
sensor, the level management board and the main board.
6. Electronics.
Replace the main board. Also, check that there is no rising steam or water flow in the electrical
compartment.
