I could tell for a couple of years that the membrane contacts were getting worn as it wold not always respond requiring me to repush buttons on the pad. Turned the unit on this spring and when it was time to turn it off, it wouldn't turn off. Doing some reading on line and others had the same symptoms. I did replace the membrane and it fixed the problem. The replacement membrane only has a six pin, but my control board is a 9 pin. As long as you connect the plug on the correct 6 pins it will work. Directions I received with the replacement kit were easy to follow, and it took me about 40 min to replace. Works great and I am back in business. Very pleased with the purchase! On a final note, I was lucky because the control board is below the membrane. My old membrane had some cracks in it and that allowed moisture to get on the control board. If you suspect moisture could be getting below the membrane, Don't wait to replace it. It could keep your control board from becoming damaged.

However, UPS told me 4 times that it was out for delivery on the truck in my town on 11 March but it wasn’t delivered until 14 March. Needless to say I was perturbed at not having the spa working for a get together. Oh well, product seems to be working fine with the short test run I performed. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/1401257-pentair-pcb-enclosure-max-e-therm-nat-lp-with-topside](https://www.desertcart.tn/products/1401257-pentair-pcb-enclosure-max-e-therm-nat-lp-with-topside) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-05-31*
