We have a Koehler jacuzzi tub that has been installed for about four years but never used. When we push the start button the jets operate for about 2 seconds.

SOURCE: Only 3 of 6 jets in jacuzzi tub working

Make sure the jets themselves are fully opened. Some models you can turn individual jets on & off

SOURCE: jacuzzi

you have to call the maker of your unit because the gasket can start leaking if you use the rong kind of cleaner

SOURCE: Jacuzzi tub works.....sort of.

motor for tub does not run checked electric its ok.. is there a reset button and does there have to be water in the tub?

SOURCE: We've had a whirlpool tub with jets for 2 years.

check behind the access door for a air tube that goes from motor switch to button if either side has come off you have to re attach it just cut off 1/4 inch of the tube before you do. that will make it fit tighter

SOURCE: Just drained jacuzzi hot tub and replaced

bleed pump check fuses and connections
