No drum in place sensor on Gene???
RA5040
Hi,

I recently started a preheat with the drum out (I wasn't entirely paying attention!). I realized my mistake 3 or 4 minutes later and stopped the machine. By that time the left hand side cover was beginning to melt.

My understanding from my supplier (BellaBarista) is that there is no drum detection switch, so that it is quite possible to run the roaster with no drum in place.

I would think that this is an extremely dangerous design flaw.

I'm not sure if I will keep this roaster because of this (if a basic safety precaution like this is not built in to the machine, what other safety features have not been considered?).

Sorry to hear this, strange design mistake indeed...
Shouldn't the thermostat engage at about 250-270C exhausted air, whatever there is drum or not ?
I thought that the thermostat is placed in the hot air path...

The issue is documented by Gene, but this not make it pardonable:

"- Do you operate it without the chamber sometimes ?
In this case the left side cover will be melt."

I've been on to Bellabarista and they are kindly sending me a replacement cover. However they say that the instruction manual clearly states that the machine should not be started without the drum in place (which it does). They also said that the cover would not go on fire.

I don't think that is good enough though, so I have asked them to report the issue to Gene Cafe. Even if the cover does not go on fire, there is wiring/electronics behind the cover which would certainly melt and possibly catch fire. At any rate there is the strong possibility of a machine write-off.

At the very least there should be a micro-switch or other sensor to prevent operation with the drum out.

I'm not expecting any reply from Gene ... but it would help if anyone who has a Gene contact their supplier asking for this issue to be fixed.

Cheers

Robert
