Viqua Sterilight BA ICE SWhat does your Sterilight ballast fault code mean? Well, unless it’s one of the following it’s likely that you’re reading the display upside down (Yes this happens ) and that LEE is actually 337 days left on your countdown. These methods are still true for Viqua fault codes as well so if you see the A3 fault on a Viqua controller then carry on.

A3

The Sterilight A3 fault means that your lamp’s 1 year lifespan has been spent. You will need to order a new lamp and reset the controller to fix this code.

A2 – UV level alternating

Your lamps output has dropped below 50%. You will either need to clean your quartz sleeve with an acid based product, clean the sensor head or clean the window the sensor looks into. If all this fails, you will need to replace the lamp. You need a UV sensor on your unit to see the Sterilight A2 fault code.

Low UV level

This is limited to the fancier controllers that have a different display. Either your unit is not powerful enough to treat the quality of the water running through it or once again, your quartz and sensor peripherals need cleaning. Water quality may need a test or re-test to come to a conclusion on this. We usually find this happens the most when people go for a smaller unit than they need trying to save money, only to fail their water test later.

Blank LED display

So you’ve switched your Sterilight controller off and back on again and the display is still blank. Fear not, the most likely reason is that you have a faulty lamp and that it needs replacing. Please make sure your unit is plugged in and that it has power going to it though. On very rare occasions, the internal fuse may have blown on your controller. This is not replaceable and you will need a whole new ballast if that’s the case. You’re roughly talking about 1 in 100000 for that though!


I can assure you, these are the only fault codes Viqua and Sterilight units are programmed to show. You can ring me up and talk about how your one is not on this list but I will debunk your different fault code theory and tell you your controller is broken. Feel free to get in touch if you’re unsure  Here

What does error 0374 mean?. Our lamp went out, so we replaced it and now it’s still beeping and says 0374. After the lamp went out I suggested unplugging the unit, since it wasn’t working, anyhow, but my husband left it beeping for 5-6 days. When he replaced the bulb he said the unit was very hot. What’s wrong – is the fan out causing overheating? Is there a wiring problem or the bulb bad?? HELP!

I changed my bulb and got all the correct displays on the controller then the next day it started beeping so I reset the controller again and the reset was faint on the display and the 365 was faint and only came on for a second then the screen went blank. Did a couple of more resets with the same results. Is it the controller that is bad, it has only been 3 years since the unit was installed. What is the life of a controller?
