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.
