Jetted bath tub has stopped working - motor hums, will not run
Unfortunately I did not know that it was harmful to use bubble bath or oils in our jetted tub. It always worked fine until the last time we attempted to turn it on. Now the motor will not run and just hums loudly. I disassembled it and the impeller will turn - albeit very slowly with a good amount of effort. Can I reasonably assume that the motor is shot and needs to be replaced? Or is there any smaller part that may have failed and negate the need for a whole new motor? I really would rather avoid calling in an electrician to look at it since I can order and install a new motor myself. Thank you all for whatever help you can provide.

The shaft on the motor should spin freely as should the impeller when attached to the pump. If there is drag on either, replace the pump and motor assembly. I have worked on jetted tubs for the past 5 years, I have seen seized pumps more than once.

Always clean you jet tub as directed by the manual. If you don't have one, than fill tub above the jets, add liquid dishwasher gel (not tabs) with bleach and run through the jets for 20 minutes. Drain, fill with clean water and run two times to clean the tub and jets and then use. Be sure your metal filter is clean of hair and soap debris. This will keep your tub and jets nice and clean. Also recommend using Epsom salts and either essential oil of lavender or eucalyptus to your bath. Both essential oils have antibacterial properties. If you want it simpler, purchase Dr. Teal's lavender soak from the drug store. Happy soaking!
When the bath pump runs and you get no water going through the jets in your bath Jet trim then the impeller has probably spun off the shaft of the motor.You will not know if this is the case until you take the bath pump out and remove the front cover of the bath pump and check the impeller.If this is the case it usually has to be replaced.
There are several cleaning methods on the internet. I would contact the maker of the tub and see if they have a cleaning agent. I know that Jacuzzi and Aquatic industries have a cleaner that works rather well. I have seen one on the net that uses 2 teaspoons of powder dishwasher soap mixed with bleach. I have not tried this one so don't know how well it works. The ones from the tub companies are not cheap, but if you want something that is going to do the job, spend the money.
The soapy water will fill all of the jets, tubes and the pump assembly. Will it hurt the tub if the jets are not running? The soap film will build up in the jets, tubes and pump assembly and can possibly cause damage if the tub is run at a later date. Contact the tub manufacture and see if there is a safe bubble bath you can use.
Bubble bath is definitely out of the question. Provide any of the products that you are using do not have a detergent base or bubbles so to speak, you can use them. Depending on how many times a week you use it you might want to get a cleaner that they use on hot tubs from you local pool distributer. I hope this helps you.
When a motor hums, it usually is the result of what is called "locked rotor." This can occur when the motor's brushes remain on one pair of the commutator contacts. The magnetic field does not shift to the next set of windings and the rotor is locked in place by the unchanging magnetic field.
If you have access to the motor, turn on the power briefly and place your hand gently on the side of the motor. Probably you will feel the vibration of the hum you are hearing, together with some heat. In locked-rotor condition, the motor draws high amperage and heats up quickly. Turn off the power.
If this is the condition, the motor is shot and needs to be replaced. You should copy down the information from the name plate (model and serial number, manufacturer, horsepower, amperage, etc.) and contact the manufacturer or a local appliance parts store about a replacement.
As you said that you recently bought the house, you may have a home-owners warranty which may cover the appliance.
whirlpool tub has jets that circulate the water, where an air bath uses bubbles that rise gently from the bottom of the tub. Whirlpools are typically used for therapy, air baths are used for a much gentler experience. Air baths can be used with aromatherapy/essential oils. Both offer a spa-like experience.
