Your sensor is not functionning , your hut tub runs for too long , is you filter clean ? It scould be a low flow of your water through the heating element, but you would have noticed that.

Hi, You need to make sure the drain hose is as high as the top of the washer. If the drain hose is to low, the water wil drain out before it reaaches the proper water level.

Please let me know if this helps you or if I can assist you further.

When the car is completely cool,check the electric fan(s) for smooth rotation.

Clean/check/change the thermo sensor,contact and wire.

Excavate air pocket in coolant system / check for head gasket leak

This test will kill two birds with one stone.

===

MAKE SURE THE COOLANT SYSTEM and ENGINE IS COLD!

RAN THIS TEST IN A WELL VENTILATED AREA ONLY!

You will spill some coolant during this air pocket purge test.......BE KIND TO THE ENVIRONMENT and ANIMAL please clean up after the test!

===

Put the front end on a pair of ramp or park your car on a VERY STEEP HILL (radiator facing top of the hill) .

Top of the coolant reserve tank

Let it ran for 10-15 minutes.

Monitor for air pockets escaping from coolant reserve tank.

Small amount of bubbles is OK at 1-5 minute mark

After the thermostat open up (after 195 F warm up) at
5-12 minute mark or after high idle you should see less bubbles.

If you do not see any in rush of bubbles then your thermostat may be partially stuck or rusted badly inside the thermostat hosing.

Give the thermostat host few gentle taps.

If you see larger bubbles surfacing after 15 minutes then should do a hydrocarbon (HC) dye test to test for potential head gasket leak.

Let engine cold down and top off coolant reserve tank.

Start monitor for coolant lost

===

A coolant flush is require every 2 years or 24,000 miles.

I recommend the thermostat that has a relief pop-let to reduce the change of burst radiator and coolant hoses.

Make sure you get a new thermostat gasket,black RTV and fresh coolant for the job.

I recently purchased a coleman inflatable hot tub. It takes about 4 hours to heat from 97 degrees to 104 degrees when I am planning to use it. Problem is it will not stay at 104 for more than a few...

Well the first thing is that it is inflatable and doesn't have the same insulation as a regular hot tub and number 2 keeping in a 65 degree environment on a concrete floor isn't helping either. The heater I'm certain is working but your variables are taking the positives away.

Our hot tub temp keeps dropping daily into the 90's temp when it is set at 104 degrees. When we turn the high speed blower on, it seems this is the only way we can get the temp back up to the

calcium will stick to heating element 1st and make it less able to heat water , eventually it will consume the entire surface and insulate the water from touching it and warming it and finally overheat it and cause burnout , high calcium (limestone) is usually a condition that occurs when filling via a well or stream , consider getting a load of pre softened water from a municipal water system , there should be a list of haulers in your area that can provide this service

Code so when runs keep shuting off then over heat code so

not too familiar with that brand. If so is error for overheat check filters or run it without. filters could be clogged and is a common cause of overheat error code. Check circulation pump and make sure its working. Also if you recently drained and refilled you could have created a air lock that doesn't allow the pump to move water and its easily fixed by loosening the discharge end of the pump until the air comes out....you will notice it right away

HI I have my hot tub at 104 but it will only heat up to about 80 degrees. what is my problem

If its set at 104, but only heats to around 80 degrees, then your heater is not working. Either the heating element is bad, or the pressure switch is not closing. The reason why the water heats up to 80 degrees, is from the friction caused by the mechanical shaft seal when the pump is running. Either way, you should really have it checked by a qualified spa technician. It is not something that the average spa owner can normally repair themselves. Sorry.

Pump is running ever 5 minutes. The heat in the

Sounds as if the 'mode' for the tub is set to sense the temperature of the water. see if there is a setting on the control box to a 'timed' setting for filtering and heating instead of controlled by the temperature setting. the problem is the the control box is away from the water and when it calls for heat it is because the water is cooler there than in the hot tub. so when it calls for heat and the water starts to circulate it gets the hot water from the body of the hot tub and then shut down because it senses the 'hot water'. make sense?

Hot tub won't stay at set temperature

I have a 2002 Infinity 6 man spa that I just got from a friend. I am also an Electrician. I had to replace the Spa pack because it wasn't working. Once I replaced the Spa Pack and used the tub it got up to temp no problem but once I got in the temperature slowly dropped and it couldn't keep up. After some research and discussion with a pool tech I found out that there is a jumper on some spa packs. It is a LC (low current) / HC (high current) jumper. It limits the current (amperage) that your tub draws. If you are running it on the LC setting it keeps the tub at low current by not running the heater when the jets are on. (this way it keeps the current low by running one only at a time) If you set it for HC it will allow high current to be drawn and let the heater and the jets be on at the same time. On my spa pack it is P26 Jumper. I have found it is also listed as Jumper 4 on some spa packs. the jumpers are located in the lower right of the circuit board. Make sure you shut off the power to the tub and know what you're doing before you attempt changes. you can also google "Gecko Spa Pack Service Manual" and you will find the manual for your tubs spa pack. Good luck.
