Re: Sherwood comercial glass washer fault help!
If its in a hard water area and the water softener hasn’t been used or there isnt one sounds like the tube which supplies rinse jets and is part of the boiler is blocked with scale,was there scale in the boiler when you fitted element? if so it’s a sign/possibility.
I use a wet pick up vac to pull the water out of the boiler and also the limescale.
Also check for hairline cracks around the heater fitting,they often stress at that point.
Which model? the boiler can be removed and descaled.
