  • Over time, the antifreeze breaks down and may freeze during a harsh winter. When the antifreeze is broken down, it turns to the consistency of soup and becomes more difficult to pump around the system
  • Temperature sensors can become faulty and can give false readings if they are heated beyond their recommended temperatures
  • Sensors can sometimes be pulled out of the correct location in the cylinder if they are not secured properly.
  • Software may need to be updated on the controller if it’s outdated.
  • Non return valves may become blocked with dirt if the antifreeze is not changed regularly. (recommended every 5 years)
