Hot tub problems we fix
Find your symptom or error code below. Each page gives you the likely cause in plain English, whether it's the pump or the heater, and the flat price to fix it.
Almost every hot tub failure traces back to one of two things: the heater that warms your water or the pump that moves it. The error code on your topside is just the control board's best guess at which one — and it's often pointing at the symptom, not the cause.
Tap your symptom below for a straight answer and a flat price. When you're not sure, call us — a $69 diagnostic settles it for certain, and it's credited to the repair.
Pick the symptom that matches
Won't heat at all
A burned-out element, a tripped high-limit, or a bad flow switch or sensor.
HeaterHeats, but only lukewarm
A scaled or failing element, scale in the tube, or a weak circ pump.
HeaterHeater not working
The element, high-limit, flow switch, sensor or relay has stopped firing.
HeaterKeeps tripping the breaker
A grounded heater element or a shorted pump winding.
PumpFLO flow error
The flow switch can't confirm water past the heater — often just a dirty filter.
HeaterOverheating (OH / OHH)
Low flow, a bad temp sensor, a stuck relay, or scale in the heater tube.
PumpHL / persistent low flow
A pump not pushing water past the heater — most often the cause.
HeaterSensor error (Sn1 / Sn3)
A temperature or hi-limit sensor reading out of range, or corrosion at its connection.
PumpDry error (dr / dry)
A dry-fire warning — low water, an air lock, or a clogged filter starving the pump.
HeaterHeater element replacement
An element that has failed open (no heat) or grounded out (trips the breaker).
PumpPump won't turn on
A dead capacitor, a failed relay on the board, or a burned-out motor.
PumpPump hums but won't spin
A failed start capacitor — cheap to replace — or a seized bearing or dead motor.
PumpPump grinding or screeching
Worn motor bearings or a dry shaft seal — often a wet-end rebuild.
PumpPump is leaking
A worn shaft seal, a union o-ring, or the volute o-ring.
PumpLow flow, weak jets
A failing pump, an air lock, or a clogged filter or impeller.
PumpNo jets at all
A failed pump, an air lock after a refill, or a clog.
PumpAir lock after a refill
Trapped air after a drain or refill stopping the pump from priming.
PumpCirculation pump replacement
A weak 24/7 circ pump that feeds the heater — causes FLO, HL, OH and lukewarm water.
Answers before you call
Yes. Most spas run Balboa or Gecko boards, so codes are near-universal even when the label differs. Tell us the code and brand and we'll know where to look.
Many codes can be either — a low-flow code, for instance, can be a weak pump or a scaled heater. Our $69 diagnostic isolates the real cause before any work.
We'll diagnose it for $69 — credited to the fix.
