I own a coffee/espresso truck here in Louisville, KY. This winter has been worse than normal and it's been giving me a lot of trouble trying to keep heat going so that we don't freeze the inside of the truck.. Anyways, heat ended up going off in our truck the other night (ran out of propane) and the truck fell below freezing. Next morning I go out there and see that my pump and boiler gauge are completely haywire. I re-filled my propane unit and immediately put some heat on the machine. Within a half hour, the steam pressure went back to normal, however the BAR pressure hasn't changed from its reading of 18 BARS.

I went on to check to see if the machine would still pull ok shots and maybe it was just a frozen gauge.. Unfortunately not that simple. Now the machine will not generate enough pressure to get through the puck of coffee. Machine warms up fine, I can hear the machine draw in water, but my gauge is not coming down from the 18 and it doesn't move when the water pump is on either.

I had heat on the machine nearly all day yesterday and nothing has changed. Draining water out of it hasn't changed anything either. Does it sound like I destroyed my pump? I would hope that if it did freeze inside of it that it would eventually thaw out..

Anyone have any advice as to what I could do or try? I was thinking about adjusting the pressure higher in case the ice may have caused some sort of issues. Otherwise, I think Im going to need a new pump.

Thanks for any info that could be given.

just messed with a few more hrs, pump continuously kicks on and off.. small amount of water comes out when i try to pull a shot, sometimes only steam comes out of the groupheads.. seems like the pump is no good now.. would the new pump correct my gauge or is that shot too?

It sounds like there are several things that have been damaged.
Freezing while it has water inside, can do LOTS of damage. Like your home, split tubes, damaged boiler, bent gauges and more.

Sadly, you are going to need to trace things system by system, item by item. Sorry.

taking it in to get looked at tomorrow. they have a rotary pump at the shop for our machine, hopefully that's our only problem. gauge still hasn't come down from 18, but appears to acknowledge pressure when plumbing is hooked up vs not. odd thing is when the pump gets turned on to draw a shot, the gauge doesnt move which I can only think is from weak pump pressure. bummer.
