📹 Expobar Office Lever and Office Lever Plus: Hot Water Flow Issues

Troubleshoot hot water issues with the Expobar Office Lever and Office Lever Plus.

There is no water coming out when I open the water valve

If you are experiencing issues with flow from the hot water arm on your Expobar Office Lever or Office Lever Plus, most likely the arm is blocked and needs to be cleaned. First, check that the steam valve works, and the issue has been isolated to just the hot water side of the machine. Also check your steam gauge. The gauge should show bar pressure, usually in the 0.9-1.2 range which would confirm the boiler itself is getting up to the proper temperature and pressure. 

Is it showing around 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 and milk debris 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 backflushing powder for ten minutes.

  • No. Allow 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. Should be sent in for repair/descale of hydraulic system.
