Trouble

We seem to have had this coffee maker for ever and the time had come for a new seal. I took it to the coffee shop and they measured it for the correct sized seal - it has not worked properly since. Every day l have tried taking out the seal, putting it back in and tightening the top half, l even rang and spoke to the coffee shop who seem mystified. Yesterday voila! it started to work again and coffee is coming through, breakfast is complete.

Sleet (meant to be heavy snow but revised) temp 3° feels like -1°
