How to repair Ulka EX5 pump  

Looks like my Bezzera Unica is back in working order. Thank you!

0:47 I replaced the Big O-ring to fix the problem. Thank you so much!!!

Thank-you for this! Helped when my pump inhaled some chrome plating from the e61's mushroom

Mine is causing the circuit breaker to jump. Any obvious fix or just better to replace?

It is compatible with Oscar 2 right?

For puzzi 8 ,?
