Reviving an ECM Giotto

Recommended Posts

Hello all

Haven't posted in here for a long while, but thought you might be interested in the ECM Giotto I recently picked up on eBay (sorry to anyone I bid against!).

It was described as not working and in need of a service, but I took a punt on it just needing descaling rather than all the electrics failing or worse. 

Anyway, I picked it up at the weekend and signs are positive so far. Electrics are fine, boiler comes up to pressure and stays there, steam wand and hot water tap are absolutely fine.

When I pull the group lever, however, the pump activates but nothing comes out of the group. Once I've had time to pick up a larger wrench, I'll take the mushroom apart and imagine I will find the issue there. There was noticeable scale in the water tank on the water level sensors, so all signs point to limescale so far!

I have also noticed some scratches to the bolts around the group lever where it looks like someone struggled to take the assembly apart. the group lever also doesn't pull down fully in the off position (as you can see in the picture) but this doesn't seem to affect functionality so far. 

This is my first proper E61, so feel free to suggest anything I should keep an eye out for once I have time to start disassembling...

If you're interested I'll update with my progress!

How’s the pump sounding? If it’s a dull sound it could just need a new pump

Only had time for a quick test, but the pump sounds good. It's filling the boiler okay, but when the group is activated the water comes straight back into the tank from the return pipe. 

Fingers crossed it's just a scaled group...

Okay, got into the mushroom and it's very corroded. The plating is coming off on my hand.

Any way to salvage this or is it done for? Could I just soak it in citric until it's just brass left?39faab9dfd5242ed1e709c9171b22e07.jpg

Here's what I did when mine came out looking in much the same state as yours, although with a bit of searching around you maybe able to find one for less £'s and do check it'll fit OK

It doesn't matter how you get there it's only the end result that matters
