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.
