Working for a spa retailer and service center I received a lot of calls from spa owners complaining, “My spa won’t heat!” Dirty spa filters were usually the culprit and an easy fix for the customer.
Spa filters are made of a pleated mesh material and are the hardest working part of your spa. They filter the water to keep it clean and protect the equipment from damage. Insufficient water flow into the heater will prevent it from heating and keeping filters clean can help prevent expensive repair bills down the road.
So how do you check to see if the filter is the problem? It’s quick and easy. Simply remove the filter from the spa and turn the spa on. If the water flow has been restored the heat indicator should come on. Once you’ve verified that it’s working, turn the spa back off, clean the filter or install a clean filter.
Most manufacturers recommend replacing the spa filter once a year. But keeping your filters clean year round is necessary to keep your spa operating well. Make sure yours stays running by following these simple suggestions:
- Remove the filter from the spa and clean it once a week by hosing it off to clean away debris that is trapped in the folds.
- Once a month soak and clean the filter with filter cleaner to remove oil and debris. This process can take from 2 hours to overnight.
- Purchase new replacement spa filters once a year.
It’s a good idea to have a backup filter on hand to ensure that you can use your spa 24/7 while cleaning the filter. To avoid serious damage to your spa equipment, never operate the spa without a filter.
