Behmor 1600 Plus - Coffee Roaster

[shortblackman]

Thanks Andy and Mal. I've done it "the hard way", but I got going and am happily finishing my second roast for the day!

[Andy]

Yeah, we know that. I think Mal and I were only posting in the thread so when someone else finds it one day they'll see the punchline.

Glad you got it sorted, happy roasting!

[Dimal]

Got it in one mate...

Hi all, has anyone had a 1600 Plus take longer than usual to roast?

My roast times (400g, P2, A) have gone from 18-19 mins duration, to 24-25 mins. 1C was 15.5 to 17 mins, now 22-23 mins.

Same CS beans, same location/method/etc.

Any ideas?

Check the afterburner (roof heating element). Hit the cool cycle and see if it lights up.

Have you been cleaning it (particularly the area around the temp sensors) as per schedule? I'm not sure that afterburner failure would extend roasting times so much....it is more likely to cause excessive smoke after first crack....but can't hurt checking.

You can also run a system self-check

Thanks, afterburner doesn’t seem to light up...

Is this an easy fix?

[Andy]

Remove the afterburner and inspect it.

Obviously with the roaster unplugged...
Remove right side panel, left side panel and top panel.
You can get at the afterburner.

If the wire is broken near one of the terminals you might be able to reattach it.
If it's broken in the middle you can't (as the Ohms will then be too high).

You can find spare parts in BeanBay.

How do they break? Typically from someone slipping with the sprung door and it slams closed while the after burner is hot, the shock breaks the wire that's more brittle when it's hot than when it's cold.

Open yours up and post a picture of what happened for further remote diagnosis.

[shauno]

Thanks, will do...

So it’s the “hot wire”, rather than an electrical wire that breaks? If it was electrical I could probably solder or replace it...

Did this fix your roast time issue? I have just started experiencing something similar. Have done a thorough clean and still having the same issue.

[Andy]

Did you check the afterburner like discussed in most of the previous posts?
With drum and tray removed, press [Cool] and look up in the ceiling to see if it gets hot.

[gooie]

Checked and it doesn't light up or get hot. Do you have any spares in stock?

[Andy]

Check in BeanBay

This may be better placed in another forum, but what do other CSers do when they get distracted and the Behmor safety mechanism kicks in? I have had a Behmor for 6 or 7 years, well over 1,000 roasts. I've always tried to redo the batch to resurrect it, usually seems to turn out at least semi-ok. Do you do this or just chuck it out and start again? I'd be interested in your thoughts.

Did a roast (1600 plus 2-3 years old) this morning, a pre blend of Volcan and Sulawesi, 400gms starting at P2B for 20 minutes. Had to hit "C" 3 times to keep adding on 3:10minutes to hit first crack, otherwise it would have timed out, then a stack of smoke and finally hit cool. No 2C. The beans are dark and I can't tell the difference between dark and burnt. I took a photo but it made them look lighter so I didn't post it. So my questions .......
Why didn't FC happen during the 20 minutes?
Is adding 3:10s 3 times normal for some beans?
What's the difference between burnt and dark? Is it smell?
Why all the smoke?

Didn't light up, so Ill try doing what I read above

[Andy]

...and this post on the previous page might help too.

What's Behmor Err5?

On the old roasters (1600 and 1600plus)

Err5 is "too much heat on the triangle shaped housing over the circuit board"

There is a 12v DC Fan on that triangle housing and a thermistor behind it. If the fan stops spinning the housing gets hot, the thermistor triggers Err5 and the power is turned off to the elements to stop it overheating.

Possible causes:

• Dirty 12v DC Fan
• Dead 12v DC Fan
• Side circuit board problem (which drives the fan)

For testing you can remove the 12v DC Fan from the right side cover and swap it into the triangle housing. The roaster will run without the side cover fan, but not without the triangle housing one. Both fan positions on the circuit board are interchangeable too.

Fans are available in BeanBay.

Sadly, Side Circuit Boards for the 1600/1600+ are not manufactured anymore. We are still waiting on the upgrade kits which will bring your 1600 up to 2020sr current spec with a front panel, new circuit board and drive motor. When these are available they will appear in BeanBay (but I really can't guess when Behmor will produce them)
