    Grimac Boiler not heating

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight
    Grimac La Uno manual machine

    Havent had any dramas with the machine before

    Now today the boiler wont heat up

    The pump still works and the water is coming through the screen, jut not hot.

    The light at the front comes on then turns off quickly and no pressure is registering on the gauge at the front

    Whats the first steps to diagnose the problem?? Not really that handy when it comes to machines

    Thanks for any help!!

    Pressurestat or element control relay most likely. You can replace the pressurestat microswitch with a Cherry D45X. These can be bought on RS Components for a few dollars. You will also need a T10 torx driver to remove the switch from the pressurestat.
    Ensure the machine is unplugged from the wall.

    If no luck, take it to a technician as any further diagnostics/repair would be best left to a qualified person.

    Hi Matt,

    Might I suggest that this is a job for a qualified technician. 240V has produced many recipients of Darwin awards. If you don't know what you're doing, don't do it.

    Cheers

    Yeah I wouldn't attempt myself, have a contact who is very skilled with it so wanted to pass the info onto him. Not my line of work that's for sure!

    If he's a skilled technician, he won't need it!

    So a skilled technician looked it it. Boiler is leaking from bottom and element is stuck open circuit.

    Any idea where to source a boiler from????

    You only need a new boiler element and o-ring.
    The distributor should have them
