Jacuzzi Answered Questions & Fixed Issues

sounds like the recirculation pump isnt working FL1 means no Flow pump 1

ck to see if you used the correct "Grain" size sand there is no one size fits all in sand filters

some tubs have a powered blower (you can hear it) or some tubs have a venturi suction bubbler system, you will have have to pop open service cover to look to see what kind you have, venturi type most of the time are turned off or down to far and don't produce bubbles (twist knobs) powered blowers sometimes have hoses pop off there fittings

well you did not mention if this marine engine is powering a jet drive or a prop but actually it has one to four impellers on it , one is inside engine cooling circ pump on front of engine and two to three are inside jet drive pump (if equipped)

this indicates a "mechanical seal failure" this will require replacement of said seal or entire pump

the capacitor is only used on the start phase of any speed so the procedure is the same , attempt to start motor for a second or two, remove all power from motor, wait 1 minute, use old screwdriver short across the capacitors terminals, a healthy spark should result if not cap is bad , or use a professional capacitor tester (it must be removed out of circuit for this )

well fiberglass is a thing that can be repaired , if your looking for a quicky way then a hardware store that sells Boat repair (gel coat) kits is the way to go, if a more perminate repair is needed there are folks in yellow pages that use a heat process that lasts a bit longer , or entire shell can be sourced from jacuzzi as well this would have to be installed by a pro though to get it done right

if level of water inside goes down then it's a leak or heavy use!!! but if not it's just condesation this is very normal in cold climates (they sweat) thats why cedar and redwood are used most for extetiors

most breaker trips are from water leaks (inside/out and outside/in) and bad heaters in hot tubs i have found

if your tub was not used for a bit of time your gonn have to pop open the sides and have a look around , Hoses that go nowhere or loose looking are what your looking for, plus water leaks , i did have a problem once with squirels getting inside one and eating hoses off ,made nest inside and generally messed things up inside it but any wild animal could do the same thing

if breaker is tripped your gonnahave to look inside the covering to see if you have a water leak, if not it's probally your heater, they do go bad, faster if your not dilagent on your water chemistry to be perfect

gaining acess is the greatest challenge , apart from that don't use metal wrenches on plastic fiittings ,(you;ll find metal is stronger) and ck all your o-rings, MAke sure power is off to entire tub Not just pump ckt, ck voltage settings on new motor to be sure they match old one , mark wires with tape to where they came off

wow if it got that cold there id be winterizing with food grade antifreeze not just drainig it down, you could miss pockets of water here and there and produce a crack in housing someplace , as for trouble shooting a no flow situation try the ole standby method of methodical subsitution it's worked for 100 years , keep removing parts (start at suction line in pool) temporray out of system till flow starts then you know last part sub'd out was it!!!

most pumps that won't prime are not recieving a good seal on suction line (inlet) ck alll the fittings for good o-rings and ck filter lid as well , hairline cracks too can develop in hard plastic over time and rough treatment this can lead to loss of prime , one other reason and it's the most expensive reason is pump seal at drive end has went bad and sucking air if your handy with a wrench then you can source a new seal from jacuzzi if not replace entire pump (thats the expensive way)

your local jacuzzi dealer should be able to source you some parts , but i can tell you if it's only a o-ring failure these are avail from your local hardware store , as most jets are rebuildable , some are not look at back for screws to see if they are or not

the pump or the motor is hot? if it's the motor then your problem is excessive load (ie. pumpshaft tight,too high a flow,forign object in pump head) if it's the pump head then your heater is set too high or failed on constant or pump impeller is rubbing housing

waterproof grease can be used on this, it's avalble in most hardware stores in the plumbing section near kitchen faucets parts , allthough for the mechanical pump shaft seal nothing should be needed to seal this if it leaks it's bad and needs replaced , but the grease is good for the o -rings in the fittings and housing

DE filters are a picky item. if you have too much media, it will blow off. make sure to follow the instructions when doing a bump or replacement of media.

sounds like it ran dry and burned up the seals between the pump and the motor

Handle retaining nut either came loose or broke off. Check the flapper valve, if its not completely closed water will keep running out, and fill valve will stay open trying to fill the tank.
