Since your pump seems to work normally through the steam wand, but not through the group, sounds to me like a blockage somewhere in the group side.
Some other info that might help sort out the problem would help, such as;
How old is the machine,
Have you had it from new,
How much has it been used,
When was the last time the showerscreen was cleaned,
When was the last time it was backflushed?
Other CSs might have some other ideas to add.
