Thread: How to disable the drying cycle?

Hi,

Doesn't use the element for drying....just uses the heat from the water....element only heats the water.
Element -may- not even come on if you use a low temp cycle.
Disconnecting it could cause other problems if the d/w senses the element is not there....no harm in pulling off one of the wires, tape it up and see what happens.

Thanks Jeff, according to the manual, the lowest temp. cycle is "Delicate/Economy" at 120 degrees for washing, and then 150 degrees for condensation drying and "Sanitizing." In 10 yrs. with our ancient heating coil washer, we never used the drying cycle.

The built-in resistance heater is 4 times less efficient at heating water than our Geyser heat pump. I'll try to disconnect it and hope that it doesn't scramble washer's brain. Here's a great PDF service manual showing where everything is:

Could I destroy old gaskets and such disassembling it to get to the heater?

I'd disassemble nothing, remove access panals and try taking one of the heater wires off ( power off! ) and tape it up.
Might need to pull the d/w out from the opening.



Element is the upper and lower wire connectors on the right side of the pic.

Element doesn't come on during the dry cycle like others do...just heats up the water before the dry cycle.

Thanks again Jeff. I lifted out the big filter and didn't see an access panel, just the edge of a huge black gasket (6-8 in. dia.).

I don't recall an access panel on the bottom. It looked like one giant solid piece of structural plastic. Where is that panel typically found on these older Bosch d/ws?

Access panal...

Wow, looks like a bit of work! I could probably find it behind the right side panel. This Univ. of California/Davis ACEEE study did exactly that, disabled the in line water heater and measured only a 25% reduction in electrical consumption. The d/w's brain kept increasing the cycle time since it couldn't raise the temperatures. It's a great read for us DIYs: http://eec.ucdavis.edu/ACEEE/2008/data/papers/1_123.pdf

Pulling the unit out is often needed on these d/w's!
