Hener Posted March 31, 2021 Report Share Posted March 31, 2021 The old heaters had a leak that coroded the terminal can you put a meter on it, regarding the pump put a live feed to it to se if it works, the heater should not stop the pump working, also check for mice damage on the wires, if you take the cover off the main box check the relay to the right, I think there is a photo of it on here Turn it off un plug, turn back on and run through set up and tell me what works and what’s not, both by hand and with your remote Quote Link to comment Share on other sites More sharing options...
Guitar kev Posted April 3, 2021 Report Share Posted April 3, 2021 I have a chinese hot tub with GD7005 running system,had a overheat on big box pcb board so had it fixed and tested by electronics engineer and put back on,all wires stayed in the correct positions and I rewired in,turned on the main switch 32amp in hot tub housing and pump1 comes on and stays on,then if I turn on the control panel each stage has jumped a cycle except the led lights I'm confused Quote Link to comment Share on other sites More sharing options...
Hener Posted April 4, 2021 Report Share Posted April 4, 2021 It’s blown the control switch on the other box, it can be repaired but you need someone who works on electronics or pay out mega money what country are you in Quote Link to comment Share on other sites More sharing options...

Hener Posted April 4, 2021 Report Share Posted April 4, 2021 I am assuming you have the hot tub I am familiar with, could you take a photo of the 2 control box's, however I am sure its the switching unit, the replacement unit is around 3 to 4 hundred pounds, the part is under a pound Quote Link to comment Share on other sites More sharing options...

Hener Posted April 4, 2021 Report Share Posted April 4, 2021 On the box on the left is it one of the relays burnt, one on the right maybe, can you take a close up photo of the damage, my money is on the box on the right, from the top control panel the cables run down to a part called a darlington switch, this is the switching unit, it will not show any sign's of burning, if your tub has a radio that will aslo cause a problem, I disabled mine. The pumps can be tested on the tub by simple connecting them up to a power supply for a couple of seconds, the circulating pump can seize, can be repaired but a pig to seal.

I've since fitted a new control panel and checked for air locks , the fault is intermittent and when the fault occurs the circulation pump does not work. If I set the temp for the heater to come on nothing happens until I give the main control box where the relays are a bit of a tap and the it all fires up .? Thanks Jon Mines exactly the same Quote Link to comment Share on other sites More sharing options...

Awoonga Posted August 24, 2021 Report Share Posted August 24, 2021 Hi I've got a Chinese control panel Ethink KL8-3A, everything works fine except the temp is set for 98 degrees but will only heat to 89 degrees then starts cooling down and heater will not kick in again, I have to turn it off until temp drops below 77 degrees then heater will work again any clues. Have checked water flow, filter, air locks, thermostat etc...... all good. Quote Link to comment Share on other sites More sharing options...
Richard adkins Posted January 8, 2022 Report Share Posted January 8, 2022 Hi all. Similar problem same cldf code pump and heater are both good tested separately. The controller is asking for temp a relay clicks in on the low voltage box but doesn't bring in main circulation pump relay. But if I turn 240v supply off for 5 minutes then back on the circulation relay will pull in and pump and heater will run for 30 seconds or so then drops out but controller is still asking for a temp rise. I'm guessing temp sensor is OK due to controller showing actual water temp and asking for heat on controller so not that. Also plenty of water in tub / filter also checked for air locks. Any help or advice will be appreciated. cheers Richard Quote Link to comment Share on other sites More sharing options...
