Welcome to our forum.
It wouldn't be replaced under warranty. The diverter only has a 1 year warranty. If it is just the handle and not the inner guts, go to the store and pick one up because there is no reason to make them come to your house.
I have a J335 and had service come out three times to fix the switches that switch on the air feature, or whatever you call it, that makes the jets pump stronger. It seems they get hung up and need a simple adjustment that I will try to observe this time.I wonder if the switches on jacuzzi might need some reevaluation from the manufacturer?
You can get a new one for a few dollars from JW Service at 800-541-9405.
1-year warranty? What you talkN bout Willis? 10 on structure, 7 on shell & 5 years on all controls and electrical as well as all plumbing on all Jacuzzi Premium (350 is Premium) products. BTW - Still havent seen the levels I ordered from the service company. Will be calling them in the morning to figure out what is going on.
