Espresso: Carimali Alfa

Hi

I am restoring my Carimali Alfa and in removing the element I managed to completely break it. The Alfa is a bit of an orphan and impossible to find any reference to when searching for parts. However it does appear from pictures I've seen that the element from an Uno is the same. The element is fairly standard except that it includes a Bulb Sheath for the hi-temp limit probe.

I have tried several parts suppliers online and haven't had any luck locating a replacement element that includes the Bulb Sheath - I can get one without the Bulb Sheath.

My questions are

Does anyone know where I may source an element from?

Does the wattage of the replacement element need to be the same as the original?

Can a Bulb Sheath be retrofitted to an existing element fitting?

Are there alternatives to using a Temp Probe that are easy to retrofit to my machine?

Here's a picture of the boiler with the element being the fitting at the bottom. Its 40mm to the outside of the threads, so 1 1/2".

Thanks for any assistance.

Hi,
With rare machines, sometimes you need to do the best you can. No, if the element is close to the same wattage then it should work OK, it will just heat a little faster or slower depending on which way from stock the new element is. As to adding the bulb sheath, the only time I have seen them is to mount an safety thermostat to the machine to prevent the heater element from getting too hot, if the boiler is low on water, the probe will warm up and turn off the heater to prevent damage. As long as you are close with the wattage, your wires should be OK but if the new heater is much hotter, you need to seriously look at new wires too. Then again, it is doubtful about using a heater that much bigger. Adding a sheath is possible if there is enough room on the element but it will require surgery, drilling a hole in the element and brazing a new sheath into the fitting and making sure it is water proof/ pressure proof.

There is not a lot of info on that machine. I did find this, http://coffeegeek.com/forums/espresso/questions/247757 and by the pic there, it does look a lot like an Oscar but it could be two totally different machines too with only a passing look alike.

The machine looks to be a rebranded Oscar, but the boiler configuration is different. However the element fitting does indeed look to be the same. Is it a 30mm nut? I can recommend a source for a new Oscar element which might fit, but check the dimensions first with the seller. Good luck!
