High
Low System Pressure light on Potterton Puma 100e

Your boiler has lost the water pressure it needs to circulate heat, so it has safely shut itself down until the system is topped back up.

Call an engineer soon

Book a Gas Safe engineer within 24 to 48 hours. Your boiler may be unsafe or could break down completely if left.

Technical description

The central heating system looses pressure for any reason and the appliance will cease to function.
