pb4-60 hose

My PB4-60 hose from the motor output keeps popping out of the quick connect.

Quick connect looks ok. Dont know how to fix.

There are a few vintages of that pump - the parts for the older ones (1994-2011) are here, and the parts for the newer ones (2011-Current, with serial numbers after  PB120111001 or beginning with AVEH050100)  are here.

You may need to get a new hose or coupling if it keeps popping out, and check the cleaner to be sure there are no obstructions.
