How to Diagnose My Ramco Hot Tub

Verify the hot tub is getting power if it won't start. Examine the circuit breaker to make sure the breaker is turned on and then check the fuses. Turn off the main breaker and check each fuse or circuit with an ohmmeter. If a fuse is discolored, loose or doesn't show a reading from the ohmmeter, change it to see if the tub starts working normally again.

Inspect the ground fault circuit interrupter with the power turned back on to the tub. Push the test button on the side to see if the reset button pops out of it. If it doesn't, the interrupter is likely faulty and needs replacement.

Check the control panel for error codes. This varies depending on your specific model, so check your manual if you see an error code to determine its meaning and how to repair it.

Turn up the thermostat on the hot tub if it turns on but won't heat. If the water isn't any warmer after an hour or two, the heating element likely needs replacement or the thermostat itself is faulty.

Clean or replace your water filter if the water flow for your tub is lower than usual. A clogged or dirty filter impedes the water flow and places undue strain on the pump motor.

Inspect the pump if the hot tub isn't running but you hear the motor running. Disconnect the power from the tub or shut the breaker off to avoid electrical accidents. Check the pump for blockages and remove anything you find. Hair or debris sometimes clogs the pump and shuts it down. Rotate the main shaft with your fingers to ensure it moves smoothly. If there are no clogs and the shaft moves freely, the capacitor is the likely culprit and needs replacement.

Check the valves, pipes and seals for leaking water with the power still off. Any leaking parts need replacement.
