Dishwashers normally are hot or cold feed.
My wife runs water at the sink to get it hot going in before turning on the dishwasher.
You can use either cold or hot water.
We have ours hooked up to the hot water side.
They work better hooked up to the hot water.

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.

If your heat cycle is not coming on, which it sounds like it is not, then you may have a problem with the heating system. There is a well known issue with many of the Bosch dishwashers that use the (266746) control module. Basically, there is a relay (which is a kind of electro-mechanical switch) that is used to turn on the built-in heater. There is a solder joint on the main Printer Circuit Board (PCB) that allow electricity to flow to the heater, that joint often will melt away and burn the surrounding area of the PCB. This is most likely a design flaw and appears to occur at about the 4-5 year mark. One way you can test for this is to run the onboard diagnostics routine that is programmed into the firmware of the micro-controller (brain) of the dishwasher. The way to do so it to press and hold the (Scrub Wash & Delicate/Econo) buttons at he same time and then press the on/off power switch to the on position. The LED lights above both those buttons should begin to flash, when they do, press them both again and the diagnostics program will start. It is a multi-phase program that will run for quite a while. Once it finishes, if it is a heating problem, it will end with a number 2 code in the display. If this is so, then it very well maybe the solder-joint issue on the control module and it will need to be replaced. It runs $128.10 US directly from www.bosch-appliances.com. Good luck.

Bosch dishwasher actual runtime versus indicated runtime.


The usual discrepancies with run times is due to water heating time.
For example, your dishwasher may be estimating run time + time to heat the water from cold.
If your dishwasher is connected to hot water instead of cold, it will skip the majority of the heat cycle and adjust the time accordingly.
On the other hand for other people, their dishwasher brands may say "50 minute wash" but this does not take into account heating time, so wash can be anything up to around 70-80 minutes.

Bosch SGI4345AU/17 shows 2H on the display, it does not seem to matter which program is selected, the unit runs continually. It does not heat the water or finish any cycle. The washing tablet covers the...


The Control unit on your Bosch has a burnt out heat circuit. Just about every dishwasher has a number of "thermal holds" during the wash and rinse cycles in which the controller waits for the water to be heated to a specific temperature. Most dishwashers check for a temperature rise over a certain amount of time and will shut down if this increase is not seen, however, Bosch does not employ this secondary check and the unit will run for as long as you allow.

The Control Unit on your dishwasher will need to be replaced. Being as Bosch is extremely properitary on their parts sells, it is best to actually talk to a parts supplier directly in order to ensure you are getting the correct controller. It is very important that the replacement controller is for your model #, including the /17 designation at the end. A xxxxxxUC/12 controller will not work on your model.

The Control Unit is found in one of 2 places; 1) behind the Control Panel, or 2) at the lower right hand side of the unit towards the rear. Both are relatively easy to replace.

Year old Bosch SHU33A0UC won't start. Lights on


Light's on mean you have power.

Initiate the self test program by doing the following -

To start test program, press and hold both POWER SCRUB PLUS and RINSE & HOLD program buttons, then turn unit on
by pressing ON/OFF button. When program buttons are released, lights above them will flash. To end test program, press
ON/OFF button.
To check program indicator lights (POWER SCRUB PLUS, REGULAR WASH and RINSE & HOLD), press and hold each
program button. When REGULAR WASH program button is pressed, CLEAN light also comes on.
To start testing, press both POWER SCRUB PLUS and RINSE & HOLD buttons a second time. When testing has ended
and a fault was detected, the following indicator lights will be lit:
POWER SCRUB PLUS = Heater fault
REGULAR WASH = Water filling fault (over or under filling)
RINSE & HOLD = NTC (temperature sensor) fault – note circulation motor stops shortly after it started
during an NTC fault
To check for heater, high limit or flow switch problems, start testing until heating starts. Using a meter with a current coil,
measure current going into dishwasher. If current is ~ 11 A, then heater, high limit and flow switch are OK. If current stays
at ~ 1.5-2 A, then heater, high limit or flow switch are faulty.
If water level switch (f1) has failed (opened), REGULAR WASH light will come on and unit will continually fill and drain
where testing won't be completed. If flow switch (e5) has failed (opened), water won't heat (to 150ºF) and water won’t stop
circulating. If NTC probe (f2/f4) has failed (opened), RINSE & HOLD light will come on immediately and testing will end
shortly after water has started circulating.
If more than one fault occurs, more than one light will be lit.

Let me know what you figure out. I can repair these boards most of the time.

Dishwasher stalls


If the cycle doesn't complete, check these:

Water-heating cycle
Timer
Water-heating cycle Many dishwashers heat the wash and/or rinse water to a higher temperature, as the cycle calls for it. In these cycles, the dishwasher pauses after it has filled with water, waiting for the water to reach the pre-set temperature. What happens next, depends, as follows:

  • On some units, the pause is timed and the unit continues after the allotted time.

  • On others, the cycle can't continue until the water reaches the higher temperature. If you have this type of dishwasher and the water isn't being heated (say, because of a problem with the heating element or thermostat), after the unit stops at the heating cycle, it never continues. When you repair the heating-system problem, the "cycle problem" is fixed too.

Timer Timers don't often fail. But if every other part of the dishwasher seems to be working properly and the timer knob seems to be stuck in one place--doing one function continuously--the timer may be at fault. Dishwasher timers can't be repaired. If yours is defective, replace it.

What is the amount of time for a regular wash? Time on the plus wash?


a regular wash should take about an hour and a half. plus wash would be longer only because it heats the wash temp hotter.
wash temp is generally around 140 degrees
and your rinse is around 161 degrees.

your flow through heat assembly heats the water at 2 degrees a minute. so it can take anywhere from and hour and a half to two hours for a full cycle.
try turning your sink on hot water until you feel hot water coming out then start the dishwasher so it doesnt have to heat cold water up to those temps. it should run a little shorter.

Dishwasher not drying - Bosch Integra SHU9952


Bosch generally drys through evaporation from hot water rinse. There is a common circuit board issue where a cold solder joint on the heater relay pops.The water does not heat sufficient to evaporate any longer. Consult your manual for self diagnosing trouble shooting codes or go to appliance aid.com.
If the board connection is the issue I have repaired several, however Bosch recommends replacement only and sometimes supplies the parts free.

Dishwasher runs but does not clean


Try using a cycle that doesn't heat the water. (Quick cycle?) Using high heat rinse or sanitize will stop the timer while it heats the water. The sensor may be bad.
