Bernardf Posted January 24, 2021 Posted January 24, 2021 I have a Geyserwise TSE on my electric geyser. It is about 8 months old. It has lately started showing some funny times. After I had it on holiday mode the other day, the time showed 46:27 when I turned it back on. And this morning at 08:12 its time was showing as 05:23, even though it was not turned off or on holiday mode through the night. Before this it was keeping time quite well, even during power outages. Does anyone know whether the Geyserwise has a replacable battery to enable it to keep time when the power is off? Or should I just return it as it is still under warranty? Quote
FixAMess Posted January 24, 2021 Posted January 24, 2021 Mine actually loses time like a few minutes a month, so after every 2-3 months I have to set the time again...Maybe the internal battery needs replacing (I hope!) Quote
Bernardf Posted January 24, 2021 Author Posted January 24, 2021 I have opened it up and it takes a CR1225 3V button cell. FixAMess 1 Quote

You don't need to remove it from the wall. There are 2 screws on the front, hidden behind plastic plugs. I removed the plugs with sticky tape, and opened up the front part of the enclosure. Then the circuit board is attached to the rear part of the enclosure with 4 screws. The cable can be unplugged from the circuit board. The battery was a very tight fit to get out and in. I suspect that the battery holder that is attached to the circuit board might have been designed for a CR1220 instead of a CR1225. The only difference is that the CR1220 is 2mm thick while the CR1225 is 2.5mm thick. I got a CR1225 from Builders Warehouse for R30. Makro and Chamberlain only had CR1220's. Yekeen 1 Quote
Conrad.S Posted August 8, 2023 Posted August 8, 2023 Hi. Thanks for advice of replacing internal battery. I replaced my panel battery with a 3v cr1220 yesterday but afer another spell of loadshed the panel once again displays weird times on clock i.e. 51:20. Any further suggestions as to what can be done Quote
Bernardf Posted August 8, 2023 Author Posted August 8, 2023 Maybe replacing it with a CR1220 instead of a CR1225 caused a loose fit with poor contact? Quote
KiranB Posted February 6 Posted February 6 Does replacing the battery resolve the issue of the time going off sync? The time on the Geyserwise Panel is now off/behind by about 40 mins. Quote
