Tennant M20 & T20 Fault Codes Guide


Alpha Power Cleaners are Tennant-authorised partners across the East Midlands. We supply a range of Tennant cleaning machines for hire, including floor scrubber dryers and floor sweepers.

We are proud to provide same day or next day repairs and servicing across a wide range of commercial cleaning machines. If you have a problem, give us a call on 0800 859 5151 today.

In this guide we are going to look at fault codes for the Tennant M20 Scrubber Sweeper and the Tennant T20 Scrubber Dryer.

Repairs & Servicing

In addition to supplying a range of Tennant products across the region, we also fix any problem with your unit through our specialist repair and maintenance packages.

If you’ve noticed an issue with your commercial cleaning machine — don’t worry. Our team can identify and fix any issues using the fault code as guidance. Fault codes are a series of numbers and letters that indicate the type of fault that has occurred in your unit.

To find out why your Tennant M20 or Tennant T20 is malfunctioning, check out the full list of fault codes below, along with the causes and remedies.
