Error Description Possible reasons Solution
E09
Power phase
system protect
1. wrong phase sequence (3
phase unit)
reverse any two phases
2. possible loose conection check all wires to ensure
correctly terminated
3. short circuit between
terminals +12V and E3 open
(single phase unit)
set up short circuit between
+12V and E3
EE01
Compressor
error
1. incorrect or loose wiring check wiring against
schematic and connection
2. abnormal power supply check power supply to ensure
correct voltage current etc
3. compressor failure check status of compressor
by ensuring equal resistance
across all compressor
connections
E12
High pressure
1. incorrect or loose wiring check wiring against
schematic and connection
2. low water ow volume but
still above minimum
increase water ow - check
lters, pumps etc for debris
3. Water backowing through
heater when water pump is off
check for air leaks and ensure
no water is owing
4. Fan not running Check fan is running when
water pump and heater is on
5. High Pressure switch failure check device or replace
E03
P08
Temp difference
error
Water ow failure
1. incorrect wiring check wiring against
schematic
2. obstruction in water piping
(incl. lter) system
clean water pipes - backush
system if possible
3. water ow volume under
minimum
increase water ow - check
lters, pumps etc for debris
4. water ow switch failure check, clean device or replace
