My inline rapit heater is leaking from inside control box?

remove front panel visually inspect pumps to see if leaking if ok check by control box remove cover inspect where plumbing runs through keep eliminating thing until you find it

hi,

ok so when the pump is on high and the heater is running it doesent trip? you didnt say if it did. undo the heater leads so the pump is isolated completely. run the pump on the control centers gfci and see if it trips. if it does then try wiring directly - with an extension cord to a plug with a gfci in your house and see if it trips the gfci in your bathroom. if no trip inside house then bypass tubs gfci and run it with heater and pump through your bathroom gfci. if no trip then try and replace the tubs gfci, it gets pretty humid in the control center and gfci's have a semiconductor which which do fail after years of rough duty like that. if it trips the gfci in your house with the heater again it has a cracked heater element. craigslist always has old hot tubs and parts. you might have to buy a whole used old hot tub but that may be cheaper than a new heater box.

If you currently have hot water coming to other parts of the house, and you have patiently waited for the hot water to reach the tub, then you don't have a hot water line connected to the faucet. Also, because a hot tub or whirlpool can hold more water than your water heater holds, an inline heater is often used. It attaches to the plumbing system on the whirlpool.

firs check both heater hoses are hot to the heater core after it is warmed up. If they are hot the heat cool door is not moving make sure the linkage for the actuator door is hooked up. If that isnt working test the module that moves it.If it is manually or vaccum operated there will be a heater valve inline the heater core hose. Make sure your vaccumm is supplied to the heater box from the engine. If it is staying on defrost you may be missing vaccum supply to the heater control. If it is electronically controlled the door actuator module is bad or not getting power. Sometimes the heater hand controls are the problem. sometimes the dash control separates and gives a vaccum leak.

Inline heaters for whirlpool bathtubs will not and cannot maintain any comfortable water temperature. Their sole function is to slow the time it takes for the water to cool off. The myth of their capabilities has long been a misleading sales propaganda joke in the industry.

Not all manufacturers put their model numbers on their tubs. Those that do will almost always post it on a label in the area of the tub where the back usually rests in the region of the motor but not on the motor itself.

I believe your quarter size cap is an air control for you jet. It controls the amount of air coming out the jet when the tub is full of water and the motor is on. You should see the difference in swirling water turning it from right to left or the other way around. If yours has a leak then I certainly hope you find the Model number. Good luck.

Check for a bad heater controller board or burnt wire connection going to the heater. You can check for voltage across the white and black leads going to the heater from the heater controller board (upper left corner of the black control box

I think you have a small leak somewhere that is causing the GFI to kick off. ... and it is probably quicker than 2 seconds.

Look carefully inside the control box - that is where I found the leak in mine.

After you get it fixed (and you may have to buy a new control) pat yourself on the back for having saved yourself at least $250.00.

Good luck with your project.

The heater element is located inside the stainless steel tube located under or near the main control box. Unless you have experience in replacing one of these leave it to a pro. You will have plenty of places that will sprout leaks if the replacement is not done correctly.

Make sure that the inline heater has power. It should not take very long to heat since your putting hot water into it anyway. The heater is to keep water warm.

It sounds like your inline heater has stopped working. The only way to test it is to drain the water back out, remove the inline heater, and hook power to it to see if it heats up.

If it doesn't you can get one at a discount supply house (like Home Depot or Lowes) for less than $150.
