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.

I installed a new pump motor. It has power, lights are working but jets are not. What wires could be wrong - I don't have clear red, black, white and green wires. The spa is a freeflow passport spa.

there should be a wiring diagram on the side of the motor make sure if you are running 120 volt you changed the shunting on motor or might have hooked up incorrect if no info call a professional

Installed new pump unit starts and runs for 15 minutes then trips breaker what should I check

When the pump nears the 15 minute mark, check the housing to determine whether it is running hot. Also listen for changes in pumping sounds as something may be causing restriction.

Dream maker spa x-400 won't shut off keeps heating. I have turned it off and let it tottaly cool down the temp max temp is set to 95 and it never shuts off until it gets to 105 and overheats.

I had the same problem last year, I talked to a spa guy and he stated that the temp sensor was probably covered in bio crud. He also stated that the tub should be cleaned with a hot tub flush. After doing that I have not had a problem with the temp settings.

Spa overheats

it sounds to me that you have a bad temp sensor and if it is in a portable spa, alot of the time they are built into the control board.

I have a freeflow legend hot tub. the gfi was tripping and i found the heating element was bad. i replaced the heater element now when i power up the tub a circuit breaker trips on the board and nothing...

It sounds like there may be a short in it causing the breaker to trip. I would disconnect the wires from the new element, tape them up and test for the problem again. If it still trips it is not related to the heater element. If it still trips it is not related to the heater element and therefore additional diagnostics need to be used to find out what is is wrong.

Hi have problem with canadian spa (balboa mrspa1) control panel digital reading when turned on goes to OH,circulation pump will not run

OHS, OH, or SPA TEMP LMT Message There is an "Over Heated Spa" (OHS or OH) Water Condition.

One of the Water Temp Sensors has detected 110°F (43.3°C) Incoming Water Temp and Spa Functions are Disabled. System will Auto Reset when Water Temp is below 108°F (42.2°C). Check for Extended Pump Operation or High Ambient Temp, or contact your Dealer or Service Organization.

Spa Water Cool Down
• In order for the Spa Water Overheat Error Message to Automatically Reset and Clear, the Spa Water Must Cool to below 108°F (42.2°C).
• Check the Topside Panel Display to see if the "OHS", "OH", or "SPA TEMP LMT" Spa Water Overheat Error Message has Cleared. If the Error Message has Not Cleared, the Spa Water is still too Hot to Continue Testing.
• Either Wait for the Spa Water to Cool Below 108°F (42.2°C), or Exit Now and Retest at a Later time.

Regulator free flows

A well tuned reg will easily freeflow. Try holding the mouthpiece downward and SLOWLY rotating to fill the 2nd stage with water.
If that does not stop the freeflow and/or if the 2nd bubbles even with the mouthpiece held downward, the you need to get the reg serviced.
