Re: stuck on first step of cycle (water draining)....

This may be due to a leak which you are not aware of. there is a float switch in the base which if operates, turns on the drain pump and nothing else. to check, tilt the appliance backwards 45 deg and see if water comes out of the back. if so, you are faced with identifying the leak which is often the main pump

I have a Bosch SHU3036UC dishwasher. While sitting idle - during the day or over night, it fills up with fresh water. I shut off the water supply last night and this morning it was dry. Any ideas?

Bosch shu3036uc gets stuck during cycles.


Welcome to FixYa.

Based on your description " bosch shu3036uc gets stuck during cycles

I suspect the thermostat isn't satisfied when heating the water, hence it get`s hung up trying to heat in the part`s of the cycle it`s called for.

It very well could be caused by a faulty flow switch, NTC or heater as well but not very likely.

The dishwashers made by Bosch with a rotary dial timer have very few if any, issues with the actual timer or element but they do with the thermostat within the door panel.

If it ( the thermostat ) is not satisfied the water may heat but not be indicated via the thermostat, hence timer will not advance.

Here`s what you can try. If you have any hesitation or reluctance to service this yourself please call in an authorized B/S/H/ ( Bosch/Thermador/Gaggenau ) appliance technician.

**Turn off the breaker at the service panel before attempting any service suggested **

  1. You will require a #20 torx screwdriver to remove the door panel by taking out the screws around the panel, except the ones along the top ( watch the edges they are very sharp )

  2. Once the panel is removed you should see the thermostat over by the detergent dispenser clipped to the inner door, remove it and test it. You`ll need a ohm meter/multi-meter plus a lighter or match to heat it up to see if it open`s & closes.

**NOTE** it can occur the thermostat can become loose and detach from the bracket which holds it in place, this too can manifest in the sysmptom of the timer not advancing.

Let me know how you make out and what you find.

Thank you for choosing FixYa and Good luck.

My Bosch SHU3036UC is getting stuck during the cycle. Doesn't always get stuck in the same place. Saw an answer on here that it is probably the module. Is that something I can replace myself?


I want to clarify some info with you before I give any solution advise if you don`t mind.

Have you had this dishwasher since it was new ? Do you still have the user manual ? I want to just clarify you are familiar with the "normal" operation. I hope you take that as I intend it, I mean you may in fact be completely aware of how it work`s normally, but being afar and therefore at a disadvantage than I typically would be on-site. I need to confirm before listing possible causes vs. regular functions, I hope you understand.

Does the unit alway`s complete it`s cycle eventually if left un-interrupted ? If so, how long would a regular cycle take on average ?

I`ll watch for your reply. Thank you.

Bosch SHU3036UC/U11 dishwasher does not stop filling with water

It sounds as if the main program board has developed a fault - as it should come to a complete stop. The fact it kept the water valve open with the door open is a serious fault- so I would have it checked before using it again.

Most machines have a water-stop feature - so if it develops a leak - it will shut off the water. This clearly didn't happen.

I own a Bosch SHU3036UC not draining properly

HI. check the following areas for faults.

1. Air gap / Drain hoses
If there is an air gap (located in the sink, near the faucet), check to see if it is clogged. Unscrew the top cap and see if there is anything blocking inside. Note: If there is no air gap installed, the dishwasher might not drain properly.

If the drain hose is clogged, the dishwasher would not drain. If there is an air gap installed, it is very common that a hose going from the air gap into the garbage disposer is clogged. Remove and clean the hose. Make sure to reattach the hose before starting the dishwasher.

Note: If you recently had a garbage disposer installed, it is common to overlook removing the drain plug.

2. Broken belt
Some dishwasher models use a belt to drive the pump. Replace the belt if found broken.

Note: Sometimes the belt would just come off the pump. Even though it might not be broken, it is recommended that you replace the belt, because it is probably too stretched out.

3. Pump
Some models have two impellers inside the pump - one, wash impeller, takes care of the wash cycles, the other, drain impeller, drains the water out. If the drain impeller is broken (broken blades, shaft), the dishwasher would not drain. Replace any broken pump components.

4. Drain solenoid
Some models (for example most GE dishwashers) use a drain solenoid to drain water out. Sometimes the solenoid gets stuck, preventing the water from draining out. Try to free up the solenoid. If unsuccessful, you might have to replace the pump assembly.

5. Motor
If the motor is stuck, it is sometimes possible to free it up by manually spinning the motor.

Replace the motor if defective.

6. Timer
Replace if defective (note: uncommon problem).

Bosch SHU3036UC draining on wash cycle

it is probably going to be a grimy door thermostat between the inner and outer panel. its hooked into the back of the soap dispenser. someone would have to take the outer panel off then clean wipe away the caked grime from the thermostat and put it back in its place. if this doesnt fix it then it could be a heat assembly problem or timer problem. in that case you would need an appliance tech out

It seems as if the dishwasher is stuck in discharge cycle.

It sounds like the float may be stuck in the upright position, the float is what tells the machine that the water is at the leval required to cycle, and I recently had the same thing happen to mine. The float is a movable plastic part that does exactly what it sounds like, it floats higher as water enters the machine and when the float reaches a certain leval it cuts the water off , "so you don't have a flood. Look at the bottom of your machine for a movable piece that goees up and down, it more than likelly is stuck in the up position. Meanwhile I'll look for a diagram for your machine

Bosch dishwasher leaving residue

You either need a water valve, if the dishwasher isn't filling with enough water, or you need to run a dishwasher cleaner through it.
