What have you done today in the Garden?

There was a big problem with Hotpoint tumble dryers 15 years ago, with them catching fire. This happened just after we'd bought one. I contacted Hotpoint and they said they were making some alterations to them and people who had one would get a visit from an engineer to effect these. As I'd phoned early, we got a visit within a couple of weeks.
I don't think he did much as he wasn't here long. Others waited a couple of years.
The reason they caught fire, he said, was because people couldn't be bothered to clean the lint filter after use.
It's easily done. It slots in the bottom of the rim of the machine just behind the door. There's even some little pictures on the rim telling you to do it!
It's a case of just wiping off the lint with a damp finger over a bin. A 2 minute job.
What was happening was that the lint was building up near the heater elements.

We've always followed the instructions. I also look down below the filter when I've taken it out now and again to see if there's anything down there. Occasionally I remove the flexible exhaust tube and check that out. The problem can be with those machines where people use "Softrinse" or whatever, this can leave a sticky residue in the corrugations of the tube. We've never had any problems, it's on once or twice a day.
