minimum dose size?

Jan 31, 2024 |

I use the Hario switch to brew my coffee and am trying to reduce my caffeine consumption. Hence I would like to brew smaller cups of coffee. I am currently using 10g of coffee with 160g of water. (1:16 Ratio) I am wondering if there is a minimum amount of coffee...

Crossland CC1 SH error thermal runaway temp fix

My Crossland CC1 espresso maker has been a problem child from the very beginning. The steam boiler can't regulate its temperature and it runs away, causing SH errors (steam too hot), and burning up the thermal fuse (216°C / 420°F ), which cuts the power to the steam boiler, resulting in E2 errors (steam boiler not heated up within 3 minutes).

The first time I emailed Seattle Coffee Gear and BillC about this issue, Bill sent me a new thermal fuse (Thanks, Bill!). I replaced it, the machine chugged along for a couple more months and then burned the fuse again. By that time, Seattle Coffee Gear told me the machine was out of warranty, I would have to pay an arm and a leg for their service tech to even look at it, and it would take a few months.
Also, BillC completely stopped responding to any emails or calls. Apparently this is a one-man company, he's doing the best he can, whatever. Don't expect to get any customer service whatsoever with this machine. Don't buy this machine.

But what if you already own a CC1 and it's your only espresso machine and you want to continue to make hot lattes? What if you don't want to pay hundreds of dollars to ship the machine to Seattle and be without espresso for a few months? Well then, you're on your own.

Replacing the thermal fuse is pretty easy. This thread goes into detail about it. I replaced the fuse 5 times so far. But this time is different. Now, when I turn it on, the steam boiler runs at 100% power and never shuts off. It will immediately burn the thermal fuse unless I either turn on the water or cut the power. I checked the resistance of the temperature sensor: ~100 k-ohm at room temperature, and lower resistance when the boiler heats up. Seems to be in-spec for what I assume is a 100k thermistor. The controller seems to be receiving a valid temperature reading, but it is not cutting the power to the steam boiler for whatever reason, causing thermal runaway. Maybe some component on the control board has failed. SCG would probably replace the entire board (if parts are even available for this thing anymore).

But I want my latte right now. It makes espresso just fine. No issues with the coffee boiler, just the steam. So I came up with a temporary fix. I took the power switch out of an old printer and spliced it in to the power connection to the steam boiler. That way, when I turn on the main power to the machine, I at least have a crude way of controlling the steamer temperature. As you can see in the picture, I am using a meat thermometer to monitor the temperature of the steam boiler. When I flip the switch, the temp starts rising rapidly. At 380°F the front display throws an SH error, and at 420°F the thermal fuse burns up. So when I see 300°F I flip the switch to off and open the steam valve.

It's jury-rigged as all get-out, but it kinda works, and I'm enjoying my first warm latte in several weeks. Eventually I will cut a hole in the side of the machine to mount the switch, and add a more permanent temp sensor.
