Our warranty period for the Watchman Sonic oil level monitors is 12 months. To check whether your unit is still under warranty look on the back of your receiver for a 6 digit number (under Part No), e.g. A45-2817 (28/17). If you are within 12 months of this date your unit is still covered by our warranty.
What if I purchased my unit from a Kingspan stockist?
Please send us a copy of your receipt to verify when you purchased the unit and that your Watchman Sonic is still under warranty.
