Water Chiller Fault Code

Code Fault Description Prompt After The Fault Occurs Restrict Work Objects
E1 Water temperature pobe failure

1. Check if the probe wire is damaged ordisconnected

2. Check if the probe wire end is loose

Compressor,fan,four-way valve.
E2 Water flow fault

Caused by blocked water flow, it is necessary tocheck:

1. Check if the water inlet of the tub is blocked(hair, paper towels, towels, leaves, etc.)

2.Check if the water outlet of the tub is blockedby foreign objects (hair, paper towels, towels,leaves, etc.)

3. lf there is a mesh at the water inlet, the meshneeds to be cleaned.

4. The filter cartridge needs to be cleaned orupdated.

E3 Low voltage fault The compressor pressure is too ow, resulting in no short
circuit between the low pressure detection port of the main board and the public
Compressor, fan,four-way valve

E4

High voltage fault The compressor pressure is too high, resulting in no short circuit between the high-pressure detection port of the main board and the public

Compressor, fan,four-way valve

E5 Current overload

1. Ensure smooth air intake from the back of the chiller (need to be at least 0.5M away from solid walls or solid obstacles)

2. The chiller can not work under the condition of ambient temperature higher 45°C

3. In the main interface, click to enter the settings menu and reset F11 to greater than the alarm value.

Compressor, fan,four-way valve
E6 Water pump stuck fault

It is usually caused by impurities (sand/hair/Paper towels/leaves/insects, etc.) entering the water pump.

1. Disassemble the water pump, remove the foreign objects, and then reassemble the water pump.

2.lf water pump was damaged, please install a new pump directly.

3.Check there is must be a filter element inside of filter system.

E7 No water flow fault

1. Check if the water level has  submerged the water inlet and outlet of the tub.lf not, continue to add water to submerge the water inlet and outlet.

2. If the water level submerges the water inlet and outlet of the tub, push water pipe to pour water from the water inlet into the chiller until no large bubbles appear at the water outlet, and then start the chiller.
