Should you experience any difficulty with your Geyserwise or heatpump system, kindly refer to the following error codes below, for their possible causes and how to rectify the error.

 

 

 

 

Geyserwise Errors

 

Error Code: E1 - Earth Leakage

 

Possible cause:

 

Faulty element or earth leakage (more sensitive than normal household earth leakage)

 

Actions:

 

Elements needs to be replaced. Please click here to go to our contact page to arrange for a technician to inspect the issue

 

Error Code: E2 - Dry burn protection

 

Possible cause:

 

Empty cylinder
Thermal pocket too close to element

 

Actions:

 

Check all water connnections to the geyser

 

Error Code: E3 - Sensor failure water geyser

 

Possible cause:

 

The sensor could be damaged or there is a connection problem

 

Actions:

 

Replace sensor. Please click here to go to our contact page to arrange for a technician to inspect the issue
Check electrical connections and/or plug in control unit

 

Error Code: E4 - Heating loss

 

Possible cause:

 

- Leakage hot water pipe

- Faulty valve

- Scale build up

- No power supply to the element

- Reversed thermosiphoning

- Faulty heating element

 

Actions:

 

Check all of the above

 

Error Code: E5 - Over temperature protection

 

Possible cause:

 

Geyser temperature exceeds 85c

 

Actions:

 

Open hot water tap to reduce temparature in geyser

 

Error Code: E6 - Water leak

 

Possible cause:

 

- Leaking geyser

- Valves leaking

- Overflow leaking

 

Actions:

 

Check all connections

 

Error Code: E7 - Communications failure

 

Possible cause:

 

Poor contact or damaged cable

 

Actions:

 

Check communications wire between control box and display unit

 

Error Code: E8 - Probe failure collector

 

Possible cause:

 

- Faulty sensors

- Geyser temperature over 80c

- Collector temperature over 120c

 

Actions:

 

Check that water is circulating through system

Check sensors

 

Error Code: E9 - Pump failure

 

Possible cause:

 

- Faulty pump

- Blockages in pump

- Electrical error on pump

 

Actions:

 

Replace pump. Please click here to go to our contact page to arrange for a technician to inspect the issue

Check all electrical connections

Clean pump
