[GL2000 Mach 3, heater issues]

I live in Norway.

By the way, K6 is controlled by the thermostat, not K7.

K7 is controlled by the thermostat. 
When the heater should have kicked in, I measured an open contact on K6 and a closed contact on K8. (Coil on K6 had 12Volt)

Soldered a small wire over the contacts on K6 and then the heater functioned properly. This was just a quick fix, I’ll replace all relays when received from China. Ordered them now and they will be delivered in September!? so I hope my quick fix works until then😉 Very looong lead time!

Got feedback from the supplier that K6, K7 and K8 are controlling the heater. The only thing I dont know is which relay is controlled by the thermostat. 
Any of you know this?

Anyhow I can measure which relay is activated when water temp is 15’C and setpoint is 38’C, (relay on) then turn the requested temperature below 15’C. (Relay off)

It was running fine until the heater acted up.

Have tried to find a new plug to fix the earth connection. Its temporary fixed.

I replaced both temperature sensors because they did not read the same when i put them in a cup of hot water.

Hi,

Thanks for the reply but I have already looked over the back of the circuit board with a magnifying glass and a bright light. Did not see any bad soldering points. Have order 5 new relays, so then I have to get more if I need to replace all. I was hoping to get to know where the 2 or 3 relays operating the heater was located.

Hi guys.

I am having a hard time figuring out which relay controls the heater and which relay is the thermostat.

Measuring for AC volt I have 0 volt out from the board to the heater. I have set the controller in a way that heating should start. Controller temp sat to 38’C, water temp is 15’C.

Flow through heater is ok.

I think it must be one of the small relays, but Im not sure. I think its K6 and K7 but cant find any references on internet.

When the spa is on, I measure 12Vdc for the coil on both relays. So in my opinion both relays should be energised and close the contact. Only K7 is closed while K6 is open. When I turn the power of and measure across the contacts, both are open.

Anybody know which relay is which?
