Question about Dishwashers

Open Question

My Bosch SHI4306UC dishwasher will not stop running in the rinse mode. I was wondering if it will not advance because the heater is not working well enough to increase the water temp to complete the cycle. Is this most likely the heating element and something that can be fixed by a homeowner? Thank you for your help, Steve

I have the same problem. First fault was caused by poor workmanship on the assembly of the PCB. There is a relay (the largest component on the board) which was badly soldered and caused some arcing resulting in solder splattered around the plastic casing and a lost electrical connection. This relay switches the mains voltage on to the heater i.e. 240V around 8.5A for a 2kW heater. (26 ohms suggests a 2215W heater for the case mentioned). Re-soldering this connection solved the problem for about a year. Now the dishwasher is showing the same problem. I have tested the relay and it is operational, but does not seem to be turning on during a wash cycle. A new board costs around Ā£100. Zanussi will not even provide the technical details to allow a home fix. I will post my finding if I get to the bottom of this problem. It may be to do with electrical temperature sensor. My hunch is the controlling PCB is cheaply made and will not last a reasonable lifetime. A dishwasher is in itself a very simple piece of equipment with only a few valves, a pump and a heater so should not give problems in its first five years of life subject to normal usage. I will not consider purchasing any Zanussi appliances in the future.

SOURCE: Diswasher Pump won't stop running

Introduction: This may work for your problem, but only if you're finding that you cannot get further water to flow into your machine. If your machine fills, OK, then this ISN'T a solution to your problem.

I have a Bosch SHV. My sink drain backed up, and the water accumulating in the sink then migrated to the dishwasher, through the drain pipe, causing the dishwasher to fill up and, it turned out, overflow a little. When I turned on the dishwasher, the water drained, but no new, clean water came through the hot water pipe. The drain just kept running, but nothing else happened.

Here's what happened. Under the main chamber of the dishwasher, by three inches or more, is a white plastic tray. It sits almost at the floor, and it may not be obvious that it's a tray capable of holding water. The overflow water spilled into that tray, which in turn caused a float in the far left side of the tray to lift (the way a toilet float lifts when the water fills in a toilet tank) and shut off the water intake valve (like the toilet float shuts off the toilet water flow). So long as that valve is closed, your machine will not run.

STOP: disconnect power supply at this point for safety.

To see the white plastic tray and thereby fix the problem, you'll need to take off the BLACK TOE-KICK (attached on my unit by two star-head screws at its bottom) and, possibly , the OUTER PANEL OF THE DISHWASHER DOOR (in my case, a custom wood panel (attached by a few screws through the inner side of the door, two screws that are accessed by popping off little--smaller than a dime size--covers on the sides of the doors, and then the door panel lifts up and out). (I took the outer panel off, but I can't remember if I would have had to reach into the white tray without doing so.)

Once you do that, you can see the white plastic tray. It doesn't come out--at least not without removing the entire machine--so try this. You can take your fingers and feel over and into the tray. You'll probably feel the water--I did. Look at the far left of the tray with a flashlight. Back there you'll see a flat, round, 3-inch diameter piece of white plastic sitting at the bottom of the tray. To its center is a generally U-shaped lever looking device, which, at its far left end, is connected to a red stick pointing up into the machine. When water goes into the tray, the float rises, causing the U-shaped lever to rise, causing the red stick to raise, which (though I couldn't see it) causes an electrical signal to run to, and shut, the valve for your water intake.

I took paper towels, and then a narrowly cut sponge, to sop up the water in the tray. I then took my shop vac and, using it as a blower, blew what little water was left right out. You might be able to use a hair dryer, but first sop out what you can or it'll take forever. Once you've done that, put everything back together and plug your dishwasher back in. My buttons are at the top panel. To reset, hold down the two buttons marked for clear drain for three seconds and release. You should be able to start up then. It took 15 seconds before the water started to run, but it did and the machine works fine again.

Interesting note: The valve that stopped the water from flowing in automatically opened once I got the water out of the tray. You don't need to reset the valve.

Good luck.

SOURCE: my Bosch dishwasher (shu30) sticks in the rinse

Not sure why you would want to remove the panel? When this problem occurs First try putting in diagnostic mode and going thru the cycles. Anyway the tech sheet will be located behind the panel this will walk you thru putting in diagnostic mode.
There is a series of 4 screws that hold the top portion on. These are located on the inside of the door and require a torx bit to remove. Remove the screws and then lift up and out on the cover to remove. There is not a lot of wire there so I usuall remove the lower panel also,same procedure just remove the screws and slide down slightly to remove this panel. You will have to plastic pcs that slip over the hinges at the bottom and these may fall off when removing the panel. To reassemble put lower panel on first and leave the top two screws out until the control portion is installed then put in the rest of the screws.

My Bosch she45mo6uc/50 dishwasher will not advance to the wash cycle. It makes a series of clicks, but nothing happens. It just stops. Any ideas?


The most common problem that causes this with this particular unit is the water heater unit failing. It will clod rinse but then when it fills and tries to heat the water, it senses that the heater unit isn't functioning and errors out

Bosch dishwasher stuck wash cycle


If you post your model number I and others may be able to help you further.
Short of that, it sounds like, the dishwasher stops because it's waiting for the water to get to the right temperature before it advances. If you open the door and the water is cold, you need to replace your heater because it's not heating the water. If the water is really hot, then replace the thermostat inside the door because it's not reading the water temperature correctly and advancing the timer.

My Bosh dishwasher now runs well past the 105 minutes as stated in the manual, over three hours before I intervene. It gets stuck on the wash mode, it wont drain or rinse, just runs and runs in the wash...


Hello, welcome to Fixya.

The problem you're describing is unfortunately a common one with B/S/H/ built dishwasher's. That includes Bosch, Thermador, Siemens, and Gaggenau.

Here`s the most likely reason why it has detected the error...

Even if your home water supply appears hot, it's not hot enough and must be heated by the dishwasher to insure a proper clean and dry. Most if not all manufacturer`s do this.

When it comes to your Bosch dishwasher the problem 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 why it runs forever unless pressing the two buttons for "cancel".

To repair your unit 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 just running on & on because it can`t heat to advance or until canceled.

**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 their 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**

Installing a new control will certainly remedy the problem as well but since it is typically around $170 and up just for the part, I am more likely to offer someone an alternative to buying new, hence my first reaction to mention this repair tidbit.

The control is available at most brick & mortar appliance parts stores or on-line at vendors such as "repairclinic.com", "apwagner.com", "searspartsdirect.com" etc. part number is based on your specific model number so you`ll need to provide that.

Hope this answer`s your question's, 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 to it's helpfulness to you and leave a testimony if you're satisfied.

Good luck.

The cycle doesn't seem to stop correctly. I start a load. It doesn't seem to matter which mode that I start in, but it will count-down the time, but at the end it hasn't stopped running. I've cleaned out...


Hello,

Based on your description I'd say the issue is with the control. That is what I'd be looking for if called out to service the unit with the symptoms you've described.

The issue is 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 ).

My first suggestion would be calling in an authorized bosch servicer if that is an option for you and your budget however, If you cannot afford that option and feel capable, there`s a way to visually inspect the control yourself. 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 and takes forever top finish ( 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 to it's helpfulness.

Good luck.

Bosch 5300 Dishwasher


This sounds like a thermal stop as well. The unit wants to get up to a final rinse tempurature but can't reach it so just keeps going. If you have an amp probe you can check to see if the heater is coming on in the final rinse. If it is not, could be the thermistor of even the heater.

Bosch dishwasher shu4322 has code 1 aqua sensor what is the sensor do and where is it located


Most of the dishwasher has a Thermal hold period in which the machine will not advance to the next cycle until the water temperature reaches a specific degree. it is possible that your aqwa sensor/or heater is bad OR as in most of the cases, the Timer relay that is responsible in turning the heater on is stuck open, in this case you need a new timer. So,Check Timer/Aqua sensor/Heater
