The GB5 is a multi-boiler La Marzocco with a flowmeter and a steam boiler temperature alarm. A flowmeter that stops counting leaves the machine unable to dose by volume, and the alarm warns when the steam side is outside its limits.
On a machine like this, we check the water side first: supply, filter and scale, since hard water coats probes and elements. Then we test the flowmeters, the pump and the boiler heating parts, always with the machine off and cool.
Owners can check the water supply and the filter and write down any alarm shown. Everything inside the cabinet, and any work on a boiler or valve, is ours to do. We keep the visit simple: the water side first, then the flowmeter, then the boiler heating parts.

What does the steam boiler temperature alarm on a GB5 mean?
The steam boiler is outside its normal temperature range. Switch the machine off if it keeps showing and call us. Do not open the boiler or any valve.
Why does my GB5 stop dosing on a group?
The flowmeter for that group may not be counting, or the flow is blocked. Try a lighter dose, then call us to test the flowmeter and the group valve.
Do you repair GB5 machines?
Yes. Tell us the alarm text and the group involved. We bring a meter and the likely parts, and you see the price in writing before work.
