Crossland CC1 brewhead dripping after shot

Jeff, Someone just alerted me to this thread. Sorry you are having an issue. I could not see any damage to the pump from the picture. The component in the picture that looks scratched is the thermal block for the steam. This is a cast part and the scratches you see are on the "parting line"

How do I disassemble/assemble thermostat probe?

Without seeing your existing probe I am only guessing but here goes: This item in the picture looks like a thermowell. In the past a thermowell was used to allow the temperature probe to be in the water and not on the outside of the boiler. Typically the thermowell was filled with thermally conducti...

Why do espresso machines use BSP parallel fittings?

The British Standard Pipe fitting is used in most countries where the metric system is used. The Parallel thread was a common thread used in the gas industry where a more positive seal was required. Pipe threads became a standard for all things plumbing and pneumatic around the world quite some time...

Are parts typically covered under warranty?

I can give you some first hand experiences with sending parts to customers. In my experience, most people can repair espresso machine on their own. As a business owner I have to evaluate my risk in sending parts to a customer. In some respect you take on some of the liability of this repair since yo...

Tamp or not to tamp?

First check your portafilter and basket to see if there is a downstream restrictor. There is usually just one very very tiny hole just before the coffee exits. This is what helps create pressure in the basket in place of tamping. BillC

Crossland CC1 Showing Error Code E1

Sorry, just saw this thread. If anyone else is checking, you cannot check for voltage across this component. You need to check for continuity. cafefrappe, Sorry you were not able to get a hold of me. Do you still need anything? BillC

Looking closely at portafilter baskets

One of the benefits of the VST baskets is consistency. Not so much with a one group home machine but if you have a 3 group LM machine and all three are different then you will have a hard time getting consistent extraction on all three. BillC

Autofill Problem. La Marzocco Linea. 2 group

OK, if you have an EE model and the autofill is not working then it is probably the electronics box. These can be fixed and are pretty simple. It is usually something with the power supply. Of course you should inspect the board to see if any other damage is present. Post some pics of

DIY Espresso Machine Project

The vibe pumps run on AC but act like a DC pump. Here why: The Coil had a diode inside that allows current to flow in only one direction. So, the piston is retracted during one have of the voltage cycle. Then when the current is zero the spring returns the picton to the starting position.

DIY Espresso Machine Project

The probe is controlled through a capacitive circuit. The resistive circuit is unreliable and can give false readings with water vapor. If you really want to do this then by all means research it thoroughly or just copy a circuit from Gicar or someone. You will spend alot of time tuning your circuit...
