Question about Bosch 24 in. SHU43 Built-in Dishwasher

1 Answer

My Bosch dishwasher SHU43C02UC/38 runs the quick wash cycle in an erratic way - seems to get stuck at the last stage of the countdown ("1") and, I think, goes back up and runs again. Instead of +/- 40 mins, takes an hour and a half.

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.

Bosch silence plus 50 dba has error code h01


The statement below can be found at: http://www.ehow.com/list_6978265_bosch-dishwasher-error-codes.html,

The SHU4326 and 4326 models use "Regular Wash" and "Rinse Hold" to begin the test while the other three series in this section use "Scrub Wash" and "Delicate/Econo," but all use the same set of fault codes, shown not as lights but as numbers on the Cycle Countdown display. Here, 1 is an aqua sensor fault, 2 is a heating fault, 4 is a filling fault, 8 is an NTC fault and 0 means that everything is working as it ought. During an actual wash, when you aren't testing, the Cycle Countdown display may show the letter "F," which also signifies a filling fault.

The dishwasher has been running for 3 hours and seems to be stuck on 1 minute left. Upon opening, there was sudsy water remaining in the bottom, but the dishes looked clean. The washer just won't go to...


SHU 53 MODELS To start test program, press and hold both SCRUB WASH and DELICATE/ECONO program buttons, then turn unit on by pressing ON/OFF button. Initially, control module version # will be displayed (e.g./ ?21? = version 1 with jumper). When wash program buttons are released, lights above them will flash. To end test program, press ON/OFF button. To check each program indicator light, press its button. To check Cycle Countdown display, Refill Rinse Agent light and REGULAR WASH light, press REGULAR WASH button (press Delay Start button to test Cycle Countdown display alone). Cycle Countdown display will show ?88″ when REGULAR WASH button is pressed and ?8h? when Delay Start button is pressed. To start testing, press both the SCRUB WASH and DELICATE/ECONO buttons a second time. When testing has ended, Cycle Countdown display will show a fault using codes below. If more than one fault occurs, code numbers will be added together, (e.g./ ?6? = faults 2 + 4). 0 = No faults detected 2 = Heating fault 8 = NTC (temperature sensor) fault 1 = Aqua Sensor (?Sensotronic?) fault 4 = Filling fault F = Filling fault (display occurs during wash, not test) 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), display will show fault code ?4″ and unit will continually fill and drain where testing won?t be completed. If flow switch (e5) has failed (opened), display will show ?0″, water won?t heat (to 150?F) and water won?t stop circulating. If NTC probe (f2/f4) has failed (opened), display will show fault code ?8″ immediately and testing will end shortly after water has started circulating.
