Make sure you have cleaned the Group head and that ya seal is all OK.Originally Posted by 757073666677607E776B120 link=1275607778/0#0 date=1275607778
Use teh same basket in both and try each group handle a few times..
Do it one at a time and keep a record of what went here etc.
Swapping baskets and handles should allow you to prove either
1: Dirty group head
3: Group handle
