Mike D Easly , SC September 16, 2023 Appliance: Model SHX878WD5N/11 Bosch 800 series dishwasher watertap error code no number attached 1. Called Bosch. 2. Hung up on me once. 3. Told me they could not help on second call. (Just for background, I sold appliances for many years and have sold thousands of Bosch dishwashers so was quite familiar with them, but this one stumped me.) 4. Went online to look at articles and videos about "watertap" code. 5. Found GREAT video showing how to diagnose this issue and what potential problems could be involved. 6. Went through diagnostics from video one by one and narrowed it down to water inlet valve. Video recommended AppliancePartsPros.com highly. 7. Called AppliancePartsPros.com . On hold for less than a minute with NICE hold music! 8. Ordered my part which arrived in two days. 9. Installed part from excellent instructions from video. 10 SUCCESS!!! Dishwasher works like brand new and I was able to correct some issues while I had the dishwasher out to make sure that things would even work better in the future. 11. GRATEFUL!!! For God too lead me to a great video and too such a great company as AppliancePartsPros.com! Thank you very much!!! Do-It-Yourself Rating: Repair Time Estimate: 30-60 minutes
