Any error messages on Screen or anything else fishy..?

Hi,

The issue with your Bosch dishwasher likely lye`s within`the electronic timer/control, specifically the heater relay solder joint. ( a faulty flow switch, ntc or heater can also cause this, but not very probable ). This is the purpose of the "1" indicated in the display, a heating problem.

I`d first suggest calling in an authorized bosch servicer, however If you feel capable there`s a way to visually inspect the control. It will require you to remove the control from the unit and then remove the control from it`s plastic housing and look for a burnt solder contact on the printed circuit board. This will be one of the pins from the heater relay, hence the unit sit`s at "1" ( because it can`t heat to advance or until canceled ) trying to heat the water.

**Further to this, if you or someone you know is proficient at soldering, a lot of times it can be remedied by simply repairing the solder...although Bosch recommend`s replacing the control and I don`t pretend to speak on there behalf nor do I profess to know better. This is just my experience (it work`s) and my opinion (why buy new if one can repair ?)**

**Please disconnect the power before attempting any service to the dishwasher. If you do not feel comfortable attempting this service, call a local pro, preferably one familiar with Bosch/Thermador/Gaggenau, to service your machine.**

Hope this answer`s your question, let me know if I can assist you further. Thank`s for visiting "fixya" for your repair inquiries. Please take a moment and rate this solution and leave a testimony.

Good luck.

press and hold the drain and cancell button together for 3seconds it will reset. let me know what happened.

Hose on right that comes from middle of tank is NOT a drain hose. It is a vent hose and the end of it just sticks down into the base. It is used to relieve air pressure build-up from hot water so unit does not leak.

If you wish to eliminate or reduce the volume of the end of cycle beep you can do so by powering off the unit and turning back on while holding the right button “Cancel/Reset”. The beep has 3 volumes levels and silent, press the right “Cancel/Reset” button to cycle through the settings. Power the unit back off to save you setting.

On a Bosch dw, it has a light sensor to sense soil in the water.. if the control feels that the water going through the sensor is not clean/ or clean it will add or minus time..one thing you can do is make sure that your drain line from dw to sink drain is cleared of debris.. also, make sure you clean the filter at bottom of dw and make sure its reinstall correctly if you haven't already do so.. if your dw finish the cycle and come out clean, then the time on your dw is fine,, but if it don't finish and come out dirty.. then, it could be something other, but don't know til I get the full details on problem.. help this will do it for ya.. good luck.. mike

Make sure that the drain hose is connected as per manufacturer instructions, and that there isn't a direct run down from the sink u-bend to the machine. The rinse agent effects dishes dry but has nothing with the water remaining in the machine. Good luck!

Since water doesn't drain out,it could be a clog in the drain line. Often the problem is at the point where the drain line attaches to the garbage disposer or household drain line. You should remove this line and clear it form any debris in the hose or the hose connection. Be sure to reattach the hose before starting the dishwasher again. Good luck!
