Why PST Customers Pick This
On the ETi 400 Parts List
Pentair lists flame sensor 462023 in the ETi 400 replacement parts, with one sensor per heater.
Also in UltraTemp ETi
Pentair's catalog lists the same 462023 flame sensor in the gas system parts of the UltraTemp ETi high performance hybrid heater.
Shows Up as IGN
On the ETi 400, a flame sensor fault shows the IGN symbol with the text IGN and disables the keypad. Pentair's reset for that fault is cycling power.
Set the Rod Gap
Pentair's ignition troubleshooting chart says to verify the connection to the flame sensor rod and set the rod-to-burner distance to 0.6 to 0.66 in.
Annual Inspection
Pentair's maintenance section includes a burner spark electrode and flame sensor rod inspection, recommended every 12 months and at the start of every swimming season.
Gas Appliance Notice
Pentair states that the ETi 400 must be installed and serviced by a professional service technician qualified in pool heater installation. Improper installation or operation could create carbon monoxide and flue gases that can cause serious injury or death, and will void the warranty.

Let customers speak for us
The process was smooth and lights arived as expected. Everything test out in good working order.
Needed to replace the control overlay on our Nordic Impulse hot tub, but could not find out the make or model number of the actual control panel on our tub. By taking measurements and photos or our actual control panel button positions and functions, I was able to narrow down the options. I ordered this overlay as the button positions seemed to be in the right positions, even though the overall size was smaller than the control panel. The overlay works, in that all buttons and functions are in the right place, and the overlay seems to have adhered well to the panel. It is not a perfect match, as it is smaller overall than it should be. But I am happy with the result and will buy an additional identical overlay as a backup in case this one, too, deteriorates at some point. Took a lot of detecting, but the result is successful!
This costume is legit. It has the sparkle, glittery sheen to it like the one used on screen! Very happy with it!!
Excellent service!
PST was great at communicating the status of my order throughout the various stages. I actually did encounter a shipment issue and they handled it without issue. I will be doing business again with them.

as described, fast shipping
My wife has RA and is always uncomfortable. Our hot tub heater failed and all the local shops were not able to assist until November. I was able to order an exact replacement part which was delivered within 3 days the hot tub was up and functioning in three days. I was very impressed with the quality and service.
Good quality just ordered wrong size and also need thicker cover
Fit perfectly, and fast shipping
Super fast shipping and reliable product !
I accidentally broke the original knob by tightening it too much. This was a perfect fit and works 100%. Fast delivery too!
Swapped out broken heater (lasted about 6 years) for this one. The instructions are for the electronics, not for the plumbing. You must get everything perfectly aligned or the plumbing may leak. I needed to loosen the electronics box to get the plumbing perfectly aligned. I have hot water again.
Great prices, fast shipping, great products
Haven't received yet but I'm sure it'll be great
