Question about Pool & Spa

1 Answer

My Apollo Spa shuts off and on when high speed is pushed. I replaced pump and it is the same. Any help is appreciated.

I filled it after being drained for the winter. It imediately tripped the 50 amp ciecuit breaker. This was a short in the heater. I replaced the heater and it turned on fine. now it circulates fine on slow speed but acts like there is an internal circuit breaker tripping whenever the high jet speed button is pushed. My local Apollo Spa shop said the motor was bad on the main pump. I replaced it ($600) ane it does exactly the same thing.

Check your voltage to that pump. If the pump is set to accept high-voltage of 240 V, and you are only providing low-voltage of the 110-120 V then you will be getting that symptom.

SOURCE: Heater not coming on.

sounds like the heater element is out. if you turn the breaker on and once the tub cycles on it trips the breaker again. it is definitely the heater element.

SOURCE: High speed spa pump shuts off

The motor may have a thermal cutoff if the motor draws too much current. Do you have a sufficient large gauge circuit supplying the motore? If not the actual voltage at the motor may drop, causing it to draw more current to make up for the loss of voltage, thereby tripping the motor's protective breaker. I assume the motor will start again after serveral minutes of cooling down.

SOURCE: I have an mid 90's Apollo Spa with a mechanical

The motor that drives the clock has a cog that drives the mech. This has probally worn and you will need a new gut for your clock. If this is a yellow dial it is probally a Intermatic timer.If you get the model number off the clock Home Depo can probally fix you up. The wires may not go to the same place's so be sure to wire to new specs. Two wires in are from the breaker and will be the line wires and the two that go to the motor are the load wires. Good luck.

Pump does not shut off and timer does not stop after the 20 minutes.

What is on?
If equipped with a Small (Laing or Grundfos branded) circulation pump, these are normally Constant Duty pumps running 24-7
If not and it is your Low Speed running, then your switching mechanism has failed. This is normally the symptom of a spa that has a Mechanical Timer. Does your spa have one? If so, it may have failed, replacement should take care of it.
If electronic, then a relay has fused together on the PCB, and the only proper repair is replacement of that Board.
Now... If you are referring to HIGH Speed (you were not very specific) then this is a problem! A serious problem that needs correction ASAP!
Because a pump that runs constantly on high speed will STILL HEAT the water long after the heater turned off! Until it boils!
That is if the high limits have failed as well, don't think it doesn't happen, it does!
A very potentially Dangerous situation.
Kinetic energy or friction of water moving through the plumbing occurs! There is a restriction of the path/flow of water through the spas complete plumbing system, but the pump pushes it still no matter what, over and over. This is energy transferred to the water.
Good Luck.

2 Speed Flo-Master stuck in high speed after turning on and off the electric

Is your switch an "air switch" ... could be you have a leak in the hose that connects from the push button to the actuator that actually does the switching. Check it out.

Pump starts switching between high and low by itself for 45 seconds, then shuts off.

Thank you for posting your question here on

Is this a two speed pool pump with a toggle switch as part of the motor or a spa pump plugged into a control that uses relays to switch from high to low?

If it is a pool pump you will need a new toggle switch.

If it is a spa unit, replace the relay.

Pump shuts itself off

Fill the tub with water, disconnect the supply pipe to the pump and ithe head of water should push out any air

Make sure you can get the hose back on easily before you fill the tub other wise you are going to get wet
