Baumatic BDI1485D4E integrated washer dryer not drying.
Baumatic BDI1485D4E integrated washer dryer not drying. I removed the top to get access to the heating bit of the machine. Ran the heating cycle but that bit remained cool (it says CAUTION HOT SURFACE). There are 2 connections next to the warning which have like a very small black button on them with 2 red cables coming off the spade connectors, I pushed both of them in and heard a click, I reseated the cables on that and noticed one was a bit black, like it had shorted, anyway when I started the drying cycle again it started heating, I could feel it. But after 5 mins it stopped heating again. Any ideas?

This thread was marked as solved. Here's a summary of the problem and the fix, generated from the discussion below.
Baumatic BDI1485D4E washer dryer heats briefly then stops drying
- The problem
- On a Baumatic BDI1485D4E integrated washer dryer, the drying heater was initially not heating. After the two small black-button devices by the heater were pressed and clicked, the dryer heated again, but only for about five minutes before stopping, so the appliance still would not dry properly.
- Likely cause
- The accepted reply identified the black-button devices as thermal overload cut-outs (TOCs). They appear to be tripping again because the dryer section is overheating. Suggested underlying causes mentioned in the discussion were the main dryer fan not running, airflow blockages, or no water running into the condenser. The exact root cause was not confirmed.
- What fixed it
- Recommended action was to investigate and rectify the cause of overheating, and to replace both TOC devices, particularly the one showing signs of overheating/blackening. The thread was marked solved, but no final confirmation of a completed repair was provided.
- Checks to try
- Heater area was checked during a drying cycle and found cool initially
- Both small black-button cut-outs near the heater were pressed and reset with an audible click
- Cables on the cut-outs were reseated
- One connection was noted as blackened/possibly overheated
- After resetting, the heater warmed up but stopped heating again after about five minutes
- Parts or tools mentioned
- Thermal overload cut-outs (TOCs)
Safety: Further diagnosis should be carried out by a suitably qualified appliance engineer.

Hi, the black buttons you describe are TOCs (thermal overload cut-outs). It's unusual for them to be resettable. It's useful, but most of them have historically been one-shot devices like a fuse. When they trip, they are gone, and need replacing. The reason for this is that they don't usually trip for no reason. The cause always requires properly investigating. This is exactly what you have found. They have tripped again because something is overheating and needs fixing.
I would also replace both TOC devices too, especially the one that looks overheated.
I have an article on Whitegoodshelp that explains the possible causes for overheating, which include the main dryer fan not running, blockages, and no water running into the condenser - Washer dryer - dryer not heating
