Why Does My Wellis Hot Tub Have Flow Errors? Troubleshooting Guide
If you're a proud owner of a Wellis hot tub, you know that it's supposed to provide a soothing and relaxing hydrotherapy experience. But when you start getting annoying flow errors, that tranquility can quickly turn to frustration. Flow errors are one of the most common problems in Wellis hot tubs, and can prevent your hot tub from heating properly or running at all.
In this comprehensive troubleshooting guide, we'll walk you through the various causes of flow errors in Wellis hot tubs, and provide step-by-step instructions for identifying and fixing the problem. With a bit of DIY troubleshooting, you can get your hot tub back to working order quickly and affordably.
What Causes Flow Errors in Wellis Hot Tubs?
Flow errors occur when there is an interruption or blockage in the circulation system that prevents water from flowing smoothly through the hot tub plumbing at the expected rate. There are a few common causes of flow problems:
Clogged Filters
The hot tub's filter is responsible for trapping debris and keeping your water clean. But over time, the filter can get clogged up with particles and prevent water from flowing properly. If the water flow is restricted too much, you may get a flow error code on the Wellis hot tub control panel.
Faulty Water Flow Switch
There is a water flow switch that monitors the circulation pump and ensures water is moving at an adequate flow rate. If the flow switch gets stuck or fails, it will shut down the circulation pump and cause a flow error.
Bad Pressure Switch
The pressure switch controls the amount of suction created by the pump for water circulation. If the pressure switch malfunctions and fails to detect water pressure changes, it can trigger flow errors in the system.
Step-by-Step Guide to Fixing Flow Errors
Before calling in a hot tub technician to troubleshoot your Wellis hot tub's flow issues, there are several DIY steps you can take to identify and fix the problem:
Check and Clean Filters
The first thing to check is whether your hot tub filters are clogged, since this is the most common cause of flow errors. Start by removing the filters from the hot tub. The filters will either twist off or pull out easily.
Rinse the filters thoroughly with a garden hose to remove surface debris. Then soak the filters in hot tub filter cleaner to break up organic gunk and limescale buildup. Let them soak for at least 30 minutes. Rinse thoroughly before replacing.
Inspect the Flow Switch
If you're still getting flow errors after cleaning the filters, the water flow switch could be malfunctioning. On most Wellis models, the flow switch is located on the plumbing line near the circulation pump.
Remove the switch cover and check for debris obstructing the switch impeller. If it looks clear, test switch function by toggling power to the hot tub on and off. If the switch doesn't make an audible click when power is turned on, the flow switch likely needs to be replaced.
Check the Pressure Switch
The pressure switch can also cause flow errors if it fails to work properly. It's located on the suction-side plumbing near the pump. Test it by very briefly disconnecting the switch wires and turn the hot tub on.
If the flow error remains, the pressure switch should be replaced. This requires shutting off power to the hot tub and draining all water before removing the old switch and installing the new one.
Other Causes to Consider
If you've cleaned the filters, checked the flow switch, and replaced the pressure switch but are still getting flow errors in your Wellis hot tub, a few other parts could be the culprit:
- Air locks in plumbing lines
- Circulation pump failure
- Heater element not working
Checking for air locks involves bleeding air from the plumbing lines by loosening fittings. The circulation pump may need to be rebuilt or replaced if not operational. The heating element can be checked with a multimeter and replaced if burned out.
Preventing Flow Errors in the Future
To help avoid ongoing flow errors and keep your Wellis hot tub running smoothly:
- Clean hot tub filters regularly every 2-4 weeks.
- Schedule maintenance checks every 6 months to inspect components.
- Watch for signs of reduced flow and faulty parts that should be replaced early.
Replacing the hot tub circulation pump impeller and seals periodically can also help prevent flow restrictions over time. And using a hot tub pre-filter or water softener will reduce debris buildup in filters.
When to Call in a Professional
While many flow errors can be addressed with DIY troubleshooting, more complex repairs like pump rebuild or replacement, plumbing modifications, and electrical issues should be handled by experienced hot tub technicians.
Wellis customer support is notoriously difficult to deal with. So if you want prompt, reliable service, your best bet is having an independent hot tub technician inspect and fix any lingering flow problems.
Persistent flow errors that cause your Wellis hot tub to stop heating properly or function erratically are a nuisance. But in most cases, the problems can be resolved by troubleshooting a few key components like the filters, flow switch, and pressure switch.
Follow the step-by-step guide outlined here to clean or replace these parts and get your hot tub working again. And be vigilant about preventive hot tub maintenance to maximize the lifespan of your investment and avoid issues.
