Spring Replacement - Coffee Maker

You love your little Drip Coffee Maker, and use it every morning. This morning you took it apart to clean it.

The little valve from the underside popped off, you finished cleaning it with an old toothbrush, tipped out the water, and found that the little compression spring - about 3 mm diameter and about 1 cm long - is now on its way to the sewage treatment plant.

Don't toss your maker!

Glue a small nut (or other metal device) to the top of the trigger. This should provide enough mass to weigh the trigger down and close up the valve.

I experimented for one day, then decided I could glue a second nut atop the first to provide more weight, and hence more pressure to close.

Here is a close-up.

Caution: the pressure provided by two small nuts will not be the same as that provided by the expansion spring, so the valve may not seal well if you remove the pot while the coffee is being made. The weight should be enough to hold in the few drops that remain once the drip-production is finished.

Perhaps you took my advice to heart and dis-assembled equipment before tossing the case; in which case you may well have a spare expansion spring sitting in your "spring jar"!
