American Standard 2748.328 Town Square 5' x 42" Air Bath Tub in White - Answered Questions & Fixed issues

sounds like the circuit board in your system is faulty

Air bath tubs have a preset time limit. it could be that it reached that limit. Especially if the lights are still lit up on the control.

Check the air vacuum switch and line as you may have a air vacuum leak. The button that controls the on and off to the jets is an air vacuum switch....It may have a slow air leak in the line or connections that is activating the on and off control

This could be caused by a faulty relay or switch in the control panel. It is best to have a qualified technician inspect the control panel and replace any faulty components. If the issue persists after replacing the faulty components, then it could be a wiring issue and a qualified electrician should be consulted.

To make the water level higher in the pan, the outlet pipe must be higher.

Adjust the float on the fill valve

Depends how old your toilet is, it may be a calcium build up problem on your little inlet pipe inside your tank, but first check your water shut off valve on left side of your toilet near the wall....It may not be open all the way OR the valve has an issue...

Hey, One thing is that maybe there might be some loose plastic shavings in the fill line. From the Factory? or maybe was inside the water line going to the toilet when you connected the line to toilet. Shut off the water and get some towels and something to catch the water and disconnect it from the toilet and use bowl or what ever to catch the water and slowly turn it on and see if anything comes out. Maybe if it is in the line inside the toilet it might fall out by lightly tapping on the fill line inside the toilet to help it fall out. Just a thought when you said it "Sings" that sounds like trash inside the line going to the filler tube and bowl, hey try it who knows it might work. Okay

Hi, First, carefully remove your tank lid, and place it where it won't break or fall. Look for a four-digit number located on the back of the tank, near the water level mark. This is your tank model number. If the number starts with a two, it is a one-piece toilet. Then....visit this link: https://www.americanstandard-us.com/parts-support/faqs/toilets Good Luck!

water level to low or drain partial clog

More likely the sensor has malfunctioned.

these are called phantom flushes. the water is slowly leaking around flapper or the is a scratch of the flapper seat. I use fluidmaster parts

I think it's not a wise decision to clean a toilet fill valve, rather than buy a new toilet fill valve and replace with the old one. Thanks.

no reset on motor ( that would not cause breaker to trip, suspect heating element, or motor is bad.
