Kohler K1338 spa tub controls messing up

It sounds like the power surge coming back on damaged the controller. Try disconnecting the mains supply overnight to fully dissipate all voltage in the electronics. It that doesn't work, this is the maker, reach out for support.

Hi Claude.
If your spa jets appear to be pulsating or pausing, first check to make sure your filter isnot clogged. If your filter appears to be okay, you should next take a look at your hot tub's water level. If there is too little water, air could be working its way into the system through the jets.

not entirely unless you turn off the pump
the jets are the way the filtered water is returned to the tub
probably a problem in the micro switch that turns on the high speed jets

they use seperate pumps and one of them is bad or needs new capacitor.

I'm going on somewhat limited information here not knowing if the tub is newly installed or if this is a spa that has been working in the past and just started doing this. It would be helpful to know if this is a recently installed pump as well. That said here are a few things to check.
If it's a new install: Your electrician has more than likely wired the spa incorrectly. Be sure that the spa pack has 220V going into the pack and that the GFCI is wired correctly.
If it's an old spa with a new problem: A lot of times a bad heater element can cause a spa to trip the breaker. If you have a bad element the spa will operate normally for about a minute when you turn the power on, then trip the breaker as soon as the heater kicks in.
If it only trips the breaker when the pump is turned on to high speed, more than likely there is a problem with the wiring of the pump or the relay on the pump itself.

Hello,
Are the jets coming on when you press the button?
Try unplug the control from the board and plug it back in.

Hi Charles Gregory.

When you clean your carburetor and remove the jet screws, you will first need to lightly seat the jet screws.
But before you lightly seat the jet screws count the number of turns it takes to seat the jet screws from their original position.
Be sure to mark the turns down on a piece of paper.
That way when you put the jets back in, you know to lightly seat them first and then turn them back out to their original position before you started.
Make sure your spring that goes on the idle screw is in place.
You can also use some "locktite" thread locking compound on the threads of the needle if the spring is missing.
Normally you will adjust your idle jet to 1/2-3/4 turn open from the bottom seated position.
Then you will re-adjust the low speed of the engine when the engine is warm by turning the idle screw in or out till the engine runs smoothly at idle speed, around 1200 RPM.
The high speed jet is adjusted to 1 1/2- 1 3/4 open from the bottom seated position, after the engine is warm.
Then re-adjusted by turning the High Speed jet adjustment screw in or out till the motor runs smoothly at high speed.
Alway use the "lightly seated" method if you have not changed the screw settings.
Please take time to rate me

This is sounding like a relay not working on the circuit board inside the control box. You will want to have a Kohler service center send someone out to have it checked. You most likely need a new control box.

This may be due to clogged jets. Also, if this is a new application....the valves under the spa may not be in the up position to release the water to run into the pump and through to the jets. It may be a top side control issue as well. Check for error codes.
