Machine completes program and ends with a beeping alarm with ‘Tap’ symbol illuminated.
Have visited machine twice and not found anything faulty. No visible leaks in base, clean filters/sump/drain pump chamber. Drain pump runs correctly when called on and drain rate seems reasonable. No issues with water fill level etc. Heats and washes perfectly.
Customer has provided photo at end of program where the water level in the sump (beneath filters) is an inch or two higher than usual. Still well below the metal mesh filter. But more than when I tested the machine, where it left about an inch of water after draining.
Any ideas, please?
