Bosch Dishwasher- E:19 Error, Causes and how to fix

Bosch E19 error is caused by a defective drain valve or in worst cases a damaged controller, resulting from a defective drain valve.

Good technician! Finally someone who knows what he is doin!

Great Video very clear, gave me all the information needed to fix my faulty dishwasher. Very detailed and I am extremely grateful.

Hi Chris Iam glad you found the video helpful. Happy to hear you managed to fix your dishwasher

[@dragangojkovic208]

Hi. I’m quite beginner in this, so during removing old one both wires got out and they are free now. Both are same color. Is it important which is on left or right side, when I put new inside? Thx for answer

[@davejones5512]

Do you have a link to show changing the board with the triacs

Hola, a mí me da 7,47kohmios, pero se va la tensión totalmente abajo.¿ Debo entender que está la electroválvula bien y el problema puede estar en la placa de CI? Gracias.

Hello, I replaced this valve (resistance was good) and still getting E19. What could be other problems associated with this code? Can I check the pump and dispenser if they are good, so at least I can isolate them. Thanks

[@madapakakapadam]

@@theoracle6005 thanks for the reply. Are you suggesting that I should wait 5 minutes after power up? Nothing is happening when the power is ON. Water is not draining, no water flow, no movement.. Just frozen and blinking E19 😅

[@madapakakapadam]

@@theoracle6005 Does the new board requires programming? Thanks a lot

[@madapakakapadam]

Ok thanks. I was thinking of ordering from ebay or something.. From bosch is expensive. No, I am not from Chennai 😅. From France.

very good presentation sir

[@theoracle6005]

Thank you :)

Hi, I changed the valve but it still gives the same E19 error. what else could it be?

[@theoracle6005]

Hi Jorge if you change the valve and its still giving the error , then its the board. It is possible that your old valve may have damaged the triac on the motherboard. Motherboard is located on the bottom RHS where the mains plug connects to. In this case best to replace the motherboard

What could be the reason for this valve failing twice in a month?

[@theoracle6005]

Is it the valve or is it board providing an incorrect voltage. Did I replace the valve like for like as there is two version from memory

[@kanalord4134]

@@theoracle6005 The valve failed, why it failed is not known. The Bosch technician had no mechanism to test voltage from Board. He is going to do trial and error method. First, he will replace the valve if the dishwasher works then it is fine. If it doesn't then he will replace the Detergent dispenser, if it works then fine. if it doesn't then he will replace the power module. Can you believe it? They have given me an estimate of 11,000 INR. From our end, we are installing a stabilizer since we seem to have high voltage in our area. But this valve is too sensitive. For the same voltage, no other electrical appliances in our home fail, but only this valve keeps giving problems. Please make this valve available for sale online. So we can replace it ourselves, rather than having to pay 800 INR service charge each time just to replace the valve. Bosch Dishwasher is getting too expensive to maintain. We are already thinking along the lines of getting a washer that is better suited to conditions in India, such as Voltas Beko IFB or even Faber. Using this machine since 2018, three valves changed!! I am still waiting for the parts, today I received a call from Bosch informing us that all the parts have not yet arrived. They have given me 04 Oct 23 as the technician visit date. Cannot say I am happy with the amount of time it is taking to fix this issue. The complaint was raised on 19 Sep 23 and they are saying they will fix it by 04 Oct 23 !!! Would truly appreciate it if you could help. Ticket Id: 475322788

Good vid, thank you, do you know what the voltage is for this relay, I thought it was 12v, but on a part I have seen it is 240v !

[@theoracle6005]

Hi Stanley The inlet valve is driven by triacs (electronic switch). In regards to the relay check the original board, usually relays are used for heavy loads such as heaters. Bosch have a variety of controllers and I would check the coil voltage on the original board and replace like for like. Relays are labelled coil voltage and switching voltage/handling current. The best way is to look up the original relay part number and this will give you the coil voltage and switched side operating voltage and current rating. On this particular board relay coil voltage is 12VDC. But do check your board and verify before replacing

[@Buzzcut223]

What is this part called? I need this for my Bosch dishwasher

[@theoracle6005]

Hi The part is called a Valve outlet for the heat exchanger. Cheers

[@sarasdeliciousfood6366]

Very nice presentation , my dishwasher is showing error code 19

[@theoracle6005]

Check drain valve

[@theoracle6005]

Has your machine been fixed Saras

[@tesla2682]

7-8 kOm is good? 0 or 200kOm is no good?

[@theoracle6005]

7.6kOhm to 8kOhm is good 0 or 200Kohm is no good

[@theinfamous201]

What board is that? The main board?

[@theoracle6005]

I was referring to the main board located at the bottom rear RHS corner of the machine. This board has the triacs that operate the solenoid coil
