My machine will heat up but when it does the steam is coming from the cap and nothing will come out the hose/trigger. unsure wether cap is relieving or if it is likely to be this gasket on the cap? The cap then cannot be unscrewed until the unit has cooled fully.

    Try a new seal and confirm it is not blocked by trying to draw water through the hose when cold.

  • I'm in a very soft water area so unlikely to be a lime scale issue. Any other suggestions? By Gavin - Dumbarton - 15 February 2016

    If in hard water the gun and spray nozzle or the boiler outlet may be blocked with limescale. Try using Stock Number: ES1541155 to clear the build up if in a hard water area.
