Learn what to do if no water comes out after opening the water valve on a Profitec Pro 500 PID espresso machine.
How To Diagnose Espresso Machine Hot Water or Steam System Obstructions
If you are not able to produce hot water from the hot water wand of your Profitec Pro 500 PID, it’s likely that it has become blocked. Follow the instructions below to determine the cause and resolve the blockage in your machine.
First, make sure that the steam valve works, and the issue has been isolated to just the hot water side of the machine.
Check your steam gauge. Is it showing approximately 1.2 bars of pressure?
- Yes. Remove the hot water tip. Open the hot water wand. Does water come out?
- Yes. Remove the tip from the hot water tap and test the flow. If flow is restored then the tip needs to be cleaned and reattached. Mineral deposits can easily collect in the screen/holes of the hot water tap, so be sure to clean these thoroughly. Soaking the tip in a solution of hot water and backflushing powder will help remove residues more effectively.
- No. There may be a blockage in the wand of the hot water tap. Clean the wand by using a pipe brush that has synthetic or plastic bristles; metal bristles can damage the wand. Then soak the wand in a solution of hot water and dish soap. Backflushing powders should not be used due to the chemicals, which can cause a reaction that will strip or change certain metals different colors, especially if any type of coating is missing.
- No. Allow the machine to cool, remove the housing, remove the copper pipe off the back of the hot water valve and check for a blockage if no blockage is present in the valve or the end of the pipe, a blockage is present on the boiler side. The machine should be sent in for repair/descaling of the hydraulic system.
