Thanks, yep can solder, cool i'll have a look

Hey guys, i have an older 2 person spa with balboa controls etc, ciec pump is on but heat led is not on. I have tested flow sensor, fine it cuts out pump if I block jets can hear click of sensor and pump turn off so flow not an issue, there is no voltage at the heater (2kw). Pretty sure it's the relay. I don't want to shell out for a new board.. So can i swap relay? Would it involve desoldering etc? Or can i add pump wiring onto pump wiring, if i turn temp down below water temp flow cuts, so obviously reacting fine, would i be correct in assuming once desired temp is reached then it cuts out the circ pump ( and would also therefore cut out heater? Thankyou
