We recently bought a house as is and there is a nice Aqua Glass jetted tub and I was so excited and could not wait to try it out, then when I filled it with water and pushed the little white button it only makes a humming noise nothing comes out of the jets. Is there anything that I can do to troubleshoot it myself or am I going to have to pay an arm and a leg to have repairman come out??? I have some access to the motor it is mounted under the back of the tub. HELP PLEASE!!!!!!!!!
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.
