Diagnosis
High pressure switch 2
cuts
1. Check whether the fan
is stuck, or replace
with a new fan.
2. Replace the main
control board
1. Check if water in valve
is closed or no water
in;
2. Check if flow switch is
blocked or damaged;
3. Check if "Y" Shape
filter blocked.

Solution
1. Reinject water or change
to a new pump of larger
water flow;
2. Change a new high-
pressure switch;
3. Change a new
filterChange a new EEV.
1. Check if the fan is stuck,
or replace with a new fan.
2. Replace the main control
board.
1. Check the water filter and
water circuit (no block)
2. Replace the PCB
