Why are my hot tub jets weak or not working?
Hot tub jets can be weak because the filter is dirty or because the jet at your seat is turned down. On the One Model, every jet except the central one turns from off to full with a quarter turn. If the jets are still weak, contact Good Hot Tubs.
What makes hot tub jets weak?
The King County public health hot tub guide, from Seattle and King County in Washington, says reduced jet action is one sign that the filter needs cleaning. The other signs it lists are water that stays cloudy after proper sanitising, and dirt or oils left on the surface after use. Weak jets together with cloudy water or oils on the surface point the same way, toward the filter.
The checks below cover the causes that have a source behind them. If they do not help, the next step is to contact Good Hot Tubs.
Could the jet just be turned down?
On the One Model, every jet except the central Everywhere jet turns from off to full with a quarter turn, like a faucet handle. A jet that feels weak may be turned part of the way. Give the jet at your seat a full quarter turn and feel the difference, then ease it back to where you like it.
If the jets are weak at some seats and not others, check the control at each of those seats. Each person adjusts the jets at their own seat, so someone before you may have turned one down.
How does the One Model's massage pump work?
The One Model has two pumps. The variable-speed pump does massage and nothing else, and it drives 25 jets. Because its speed can change, the massage can run gently or at full power. A gentle setting feels weak next to a full one, so check how the massage is set before you look for a fault.
The water-maintenance pump is a separate pump. It does filtration, ozone, salt sanitising and heating, and it runs 24 hours a day. It also runs the 4 whirlpool jets.
How do the three massage zones work with the jets?
The massage jets are split into three zones: the shuttle seats with 12 jets, the pivot seat and lounge with 12 jets, and the Everywhere jet. Zone selector valves direct the massage pump's flow between the zones, so the pump's power goes to the seats in use.
If one seat feels weak while another does not, contact Good Hot Tubs and say which seat you are in.
Is the filter the problem?
A dirty filter reduces jet action, according to the King County guide. On the One Model, the owner's routine includes checking the filter and replacing it every 3 to 6 months. The app shows the water readings and tells you what the water needs, so you can follow it between checks.
If you are close to the end of that window, or you notice cloudy water or oils on the surface along with the weak jets, start with the filter.
The rest of the routine is short. Each week you test the water with a strip, enter the result in the app and check the salt system's run time. Every 6 to 18 months you replace the salt cell. Once a year you book a check-up with your local expert, and every 1 to 2 years you drain and refill.
What else is safe to check?
The King County guide says not to run the pump or heater unless the hot tub is filled to the recommended operating level. If the water looks low, add water before you test the jets again. Write down what you see before you contact the team: which seats, which jets and what the app shows.
Repairs inside the cabinet are for the local expert.
Who do you contact when the jets still do not work?
Contact Good Hot Tubs. Under warranty, Good Hot Tubs arranges the repair. A local expert on Vancouver Island services the One Model, so you do not have to find a technician yourself.
When you contact the team, say which seats have weak jets, how the jet controls are set, and when you last changed the filter.
