Hi, I replaced an old grohe wireless pumped shower with an f digital about a year ago. It worked fine for about 6 months and then stopped. The lower segment flashed green. Grohe replaced the pump which worked for a couple of weeks and developed the same fault. The new replacement worked for a few weeks and then would switch on but not pump, in fact the pump would not start, low pressure water would come out of the shower head.
The replacement pump number 4, did the same thing so I rebooted it and it has worked for about 3 weeks.
the hot feed is off a Surrey valve. The is also a bleed valve on the hot pipe out of the cylinder but no air comes out of it. There are auto bleed valves on the hot and cold feeds near the pump, which is under the bath.

has anyone had a similar experience?

grohe customer service have been good, but ......
