Jura E8 coffee machine "Drip tray not fitted" repair - I used up all my luck

내 문제

Suddenly, yesterday morning, my Jura E8 coffee machine decided that "Drip tray not fitted" was now a thing...

...despite the drip tray most definitely being present.

At the front right of the machine, with the tray removed, I could see a slot where a flange, on the drip tray, slid in to trip a visble (white) microswitch.

I could see clearly that the switch was broken. When I pressed it with a screwdriver it offere no resistance and fell back into place with gravity (as opposed to feeling sprung).

I love my Jura and I needed coffee so my plan was to simply bypass this switch until such time as I could acquire a new one.

I had not opened up my Jura E8 before so I looked for a guide.

The linked repair guide was the closest I could find to an answer to my problem...getting to the identified cause of the problem i.e. the microswitch that activates when the tray slides into the machine.

The linked guide got me to step 6 before I had to divert.

That was fine.

That was all the help and confidence I needed to press on.

The E8's front hinges away conveniently and requires a couple of the plumbed pipes to be removed for adequate access, but taht's no issue and all very obvious.

The heater covered the area where the switch lives. I could see the switch but could not get to it.

Removal of the heater was achieved by removing two screws and it didn't require any disconnection of pipes. It simply moved out of the way.

The switch itself was held in by one screw and it too came out easily.

Luckily I had a compatible microswitch in my box of spare parts.

This box is a collection of things I have stripped off all sorts of electronics over 30 years or so (mostly in case I needed it for something on my model railroad).

The first 2 screws to remove are oval head screws.

Of course I had no tool to match these, so I used a hex socket of a suitable size and brute-forced it onto the screws.

They came out relatively easily and they were thrown away (I replaced them with ordinary torx T10 screws of a comaptible size - I didn't plan to make my life difficult in the future).

I found that placing the machine on its side, when replacing the water tank side, was the only way it would go on.

Trying this step with the machine in an upright orientation proved endlessly frustrating.

Be careful/mindful that the water tank seal needs to slide into a slot on the bottom of the water tank side panel.
