Tip & How-To about Dishwashers

Conversion chart for dH to Clark BOSCH EXXEL Dishwashers

I couldn't find any info on my new BOSCH EXXEL dishwasher the codes in the manual are all in dH (german) while the H:XX codes mean nothing unless you have this table I created here it is for you all so you don't have to worry, it has all the conversions between Clark, dH and mmol/l and mg/l if you find one that applies to you just look across the table and find your corresponding H code.



You will need to go to your suppliers own website to find one of the above numbers for the quality of water usually in mg/l they will give you this value and then you can select the H code for you area.



Water hardness is measured in either European °E (clarks) or in the German °dH( Deutsche Härte) you will find this on all Bosch Dishwashers if you water is Extremely hard then you will need to program your Bosch dishwasher using the Code H:06 to give you maximum protection, if your water like mine is Extremely soft then the H:00 works well and also saves you loads of dishwasher salt.



HARDNESS CHECK TOOL

• Clark degrees (°Clark)/English degrees (°E) conversion to mg/L calcium: divide by 0.175 One degree Clark corresponds to one grain of calcium carbonate in one Imperial gallon of water which is equivalent to 14.28 parts calcium carbonate in 1,000,000 parts water.

•Deutsche Härte (German hardness) (°dH) conversion to mg/L calcium:divide by 0.14 One degree German corresponds to one part calcium oxide in 100,000 parts of water

we just bought a new bosch dishwasher (smu50e15au). Its easy to connect to water and power, but how do we mount it to the kitchen? Instructions are in German! Thanks, Suzanne


Hello Suzanne,

Bosch installation instructions are usually multi-language. They may appear to be in German, but on closer inspection, you should notice they are written in English below the German instructions.

However, just in case you do have German only installation instructions, you can download the multi-language version by clicking on the link below. These may look to be in German on first glance, but I promise the English version is there as well.

Hopefully, you will now be able to install your dishwasher correctly. If you need further assistance, I'm happy to explain any part of the instructions (in German or English), but you're going to have to explain what "mount it to the kitchen" means. I'm afraid that makes no sense to me at all ;)

Regards,
BElectric

bosch exxel the display has two elongated boxes blank


Hi.

At a glance it looks like an electronic control board problem, what you are describing is not an error code.

Try first disconnecting power, either tripping circuit breaker, or unplugging the power cord. Keep the machine disconnected for a couple of minutes.

If that does not clear the error, try holding down the start button for six seconds, until the panel reset.

If still no luck , then the electronic control may need replacement. The part must be tested by a technician. A control assembly is expensive, and there are more parts that can cause the electronic timer to jam.

If you need to call a techncian or to buy parts you can ring the number listed on the owners manual.

Try first the reset procedure described at start.

Regards.

I suggest that you use Calgon Dishwasher ( Sodium Carbonate formula Na2CO3.) tablets in the dishwasher every week this is a brand-named water softner that is essential to be used in areas of hard water which causes calcification and catastrophic failure. Use both the salt and the Calgon to suit your hardness.

If you live in a soft water area then set code H:01 as the extra is not required and only use Calgon tablets once a week use normal salt or tablet for the other washes.

Hope this helps
