I had the same E09 showing on a Bosch Silence Plus. I looked up the code on the internet and saw that it could be the heating element, as DIY Project Help Tips suggests below, but after letting it drain the machine works again without issue until it needs to drain again, then it shows E09 and has water in the bottom. Bosch dishwasher model numbers are usually found around the top or lip of the door. One of the most common differences between dishwasher models is simply the names of the buttons. For example in the first example below, POWER SCRUB PLUS and REGULAR WASH may be called WASH and ECO depending on your dishwasher model and the country you are in.
The table lists all the main malfunctions of dishwashers and instructions for self-repair. Find the symptoms of the breakdown and read about the ways how to solve the problem in the column next to the symptom.

| Problem | Solution |
|---|---|
| Dishes do not dry | The rinse agent dispenser may be empty. Check the rinse-aid dispenser and refill it if necessary. Dishware drying can be accelerated and enhanced by opening the dishwasher door slightly and propping it open with the top rack. |
| Indicator light(s) do not come on | A fuse may have blown or a circuit breaker tripped. Check the fuse or circuit breaker at your fuse box/breaker box and replace the fuse or reset the breaker if necessary. |
| Dishwasher does not starting | The dishwasher door may not be properly shut. Make certain the dishwasher door is shut and latched. |
| Dishwasher runs a long time | If the dishwasher completes the cycle, but the run time seems exceptionally long, it may be due to cold incoming water. Before starting the dishwasher, open the hot water faucet at the sink nearest the dishwasher. Run the water until it runs hot, then turn off the water and start the dishwasher. |
| Machine cycle does not advance to rinse | The water supply line may be shut off. Check the water supply valve and open it if it's shut. |
| White spots left on dishes | More rinse agent is needed. Go to the Adding Detergent and Rinse Agent section of this manual for instructions on increasing the amount of rinse agent dispensed. |
| Water not pumped from dishwasher | Make certain the drain hose isn't kinked, clogged, or improperly installed. Make certain a portion of the drain hose is at least 20 inches above the dishwasher's enclosure floor. Filters may be clogged. Make certain the filter system isn't clogged The kitchen sink drain may be clogged; you may need a plumber rather than a serviceman for the dishwasher. If an air gap is installed at sink, it may be clogged. |
| Detergent dispenser cover will not shut | You may not be correctly shutting the detergent dispenser cover, or a cycle was not finished and should be cancelled. Go to the Adding Detergent and Rinse Agent section of this manual for instructions on shutting the detergent dispenser cover. Go to the Operating the Dishwasher section of this manual for instructions on canceling a cycle. |
| Streaks on glassware | Too much rinse agent is being dispensed. Go to the Adding Detergent and Rinse Agent section of this manual for instructions on decreasing the amount of rinse agent dispensed. |
| Rattling noises | Utensils may not be properly arranged. |
| Suds in dishwasher | You may have used the wrong type of dishwashing detergent. Use only automatic dishwasher detergents. |
| Unsatisfactory washing results | • Incorrect amount of detergent. |
| • Utensils incorrectly arranged or rack overloaded. | |
| • Spray arm rotation blocked by utensils. | |
| • Spray arm nozzles need cleaning. | |
| • Filters not properly fitted into position. | |
| • Unsuitable cycle selected |
