Bosch Dishwasher - Error 15 - Leakage into the base of dishwasher.

This Error 15 occurs when the check valve within the condenser/vapour exit air break which gets clogged with dirt and food debris just above the drain channel.
This results in leakage from the condenser into the bottom drip tray, wherein the float switch gets activated resulting in Error 15 or E:15.

Hi, thank you for sharing. I also have the E15 problem with my Bosch Dish.

Hi Mustafa
You should check the following areas for leaks for E15.
1) Sump Gasket - see my video
2) Drain Hose Orings
3) Airbreak Gasket (LHS) - also known as a condenser Gasket
4) Condenser Fill valve to chamber Gasket
5) If the small float valve in the airbreak on LHS get clogged with black debris (Biofilm) it can cause water to overflow through the channel far LHS of airbreak.
Thanks

So replace the whole plastic unit?

No you can also clean the condenser with alcohol and boiling hot water.
You must fill the path leading to the check valve and agitate until the black biofilm breaks up.
Biofilm is generally hard to move from a crevice , hence use of 100% alcohol helps in the breakup.
I generally fill the pathways and leave it for 30mins, then agitate at an angle.
Then use a 50% mix of alcohol and water to agitate and remove the remaining.
It cleans up well, otherwise it's replacing the whole airbreak which is expensive.

Hello - To fix the problem you must clean the check valve using a mix of boiling hot water and Alcohol to dissolve the biofilm in the airbreak. replace the drain hose Orings and airbreak seal.
