If the motor is very hot it could be shutting off due to a thermal safety device.

Anything that makes the motor work too hard and/or heat up will trigger this.

Blockage in the water lines
Clogged pool filter
Worn motor bearings
Lack of air flow around the motor
Weak or damaged motor windings.

A defective thermal limit switch will **** off the pump when the pump is within heat and load limits.

On leisurerite spa pool what does code 1-3 mean

If your system is equipped with a circ pump, it may be configured to work in one of three different ways: 1)

The circ pump operates continuously (24 hours) with the exception of turning off for 30 minutes at a time

when the water temperature reaches 3°F (1.5°C) above the set temperature (most likely to happen in very

hot climates). 2) The circ pump stays on continuously, regardless of water temperature. 3) The circ pump

will come on when the system is checking temperature (polling), during filter cycles, during freeze
conditions, or when the blower or another pump is on.

Hi there I have a spaform oslo.The problem I got is that the filtration sequence is running all the time the jets are constantly on speed 1. The Tub is up to temp I have no fault codes. Thanks Justin

make sure correct time is set on unit, then double check to see if filter cycles were ever change, follow manul instructions attached.

Filter Cycles
On all systems, the pump and the ozone generator will run during
filtration. At the start of each filter cycle, the blower [if
fitted] will run for 30 seconds to
clean out the air channels. Pump 2 and pump 3 [if fitted] will run for 5 minutes.
There are two filter cycles per day. The start/finish times of
each cycle are programmable. To program, follow the steps under
the heading
How to set the
time & filter cycles
on page 9, ensuring that you press
"Mode/Prog" to advance to the next setting option.
The factory default filter cycles are as follows:
The first filter cycle is automatically activated at
8:00AM and operates the pump until 10:00AM. The '
indicator icon on the control touchpad will be lit
when filter cycle 1 is running.
The second filter cycle is automatically activated at 8:00 PM
(20:00) and operates the pump until 10:00 PM (22:00). The
indicator icon will light when
filter cycle 2 is running.

Pool motor kicking the breaker only after a few minutes .

If the pool pump is running and then 10 minutes into the cycle it trips the breaker, then it is overloading the circuit. The pump is laboring, workingf too hard . The filter shoiuld be cleaned. maybe there is a blockage in the return line to the pool. the other thing could be the wire size to the pump, but you said that it was running last summer . so that should be OK

Intex pool filter/ pump just stopped working

Try giving your pump more air circulation.
Turn off pump when not around it.(should only need to run for around 3 - 4 hours on a small (kid) pool 6 - 8 hours for standard house pool
You could put you pump on a timmer - set shut off time to just before you pump shuts down.
Check you pump (when not conected to mains power) - get some WD40 into it - (salt and metal no like each other)

Hayward Swimpro Sand filter shuts off after approx 2 minutes

It sounds like the pump is either overheating or the thermal protection switch that senses the overheating situation is defective. If nothing else changed like running on an extension cord, etc, a small motor repair shop can get you back up and running fairly inexpensively.

I have a ultima pool pump on my pool that is one year old. The presure is low? We have checked all baskets and hoses all seem to be fine. Any ideas? THANKS

Are you sure this is a problem??

I always backwash when the pressure gets above 20. After a good 3 -4 minute backwash and rinse it runs around 17.86 or 18.

Now, I am talking about a pool.... in a spa I'd guess that the pressures would be lower than 17.86
