About 5 seconds of continuous failure is required to
trigger an error code. Check that the electrode pins
are touching the electrode tube or alternatively the
cables. Error code may be triggered by water with a
high concentration of salt or minerals that increases
electrical conduction and makes the circuit board
believe that the electrodes are short-circuited. In that
case clean/descale the water tank and the electrode
pins.
The uppermost, high (H) electrode has not detected
the water level within the preset time, refer to the
filling time in the configuration menu. Insufficient
water flow? Is the incoming water switched on? Is
there a gap in the electrode wire connections
GND/high? Grease on the coating surface of the
electrode pins? If there is no fault present at the
water connection, the value for the water level can
be checked in the configuration menu status during
restarting, to check that the level has changed from
low to mid/high during filling. If the level has not
changed at all from low, both the mid and high (M,
H) pins are faulty. If the level has only changed to
mid, it is only the high pin (H) that is faulty
Poor wiring connection? Check by removing and
refitting the RJ10 connector. Check that one of the
pins in the female RJ10 connector on the circuit
board or control panel may have become misaligned
or displaced, so that contact with the connected
RJ10 cable has been lost.
The sensor at the NTC input has detected
excessively high temperature in the water tank.
Check the steam pipe along its length, and its
dimensions. Check that the NTC is intact.
Resistance measurement should show approx.
10kΩ at 25˚C and approx. 677Ω at 100˚C. Also
check the water quality and that automatic emptying
is activated, so that the level electrodes are not
misleading the system due to foam in the tank so
that they believe that sufficient water is available.
Try restarting the system. Check by removing and
refitting the RJ10 connector. Check that one of the
pins in the female RJ10 connector on the circuit
board may have become misaligned or displaced, so
that contact with the connected RJ10 cable has
been lost. Check the screw terminal connections on
the sensor circuit board. Alternatively change the
temperature/humidity sensor that is connected to the
RS485 input.
Water level in the tank has been at least mid-level
when checking the tank is empty, carried out at all
emptying cycles. It must always be at its low level.
Check, is the water tank drain blocked? Is the
emptying valve operating and opening? Is the relay
on the relay board that controls the emptying valve
closing? The fault may also be caused by the high
electrode pin sensing the value as water at the same
time as the mid not sensing water, the same as the
error code (level electrodes not working, mid failure)
thereby sending unknown water level.
Requires a continuous failure of the mid electrode
pin for 5 seconds at the same time as the high
electrode pin having a value equivalent to water,
before error code will be triggered. Check the
connections between the relay board and the mid
electrode. Check if the mid electrode pins are coated
with grease. The level high electrode pins may
perhaps be in contact with GND although not a
complete short-circuit but just enough so that the
value is misinterpreted as water?
