Hello Sandra, Welcome to Fixya ! You've come to the right place. The problem you're experiencing sounds like (unfortunately) a common one. The water inlet valve has been an issue with B/S/H built ( this includes bosch, thermador, seimens & gaggenau ) dishwasher's going back to the mid to late 90's. Unfortunately I've seen some pretty serious damage over the years in extreme cases when left unchecked for several days...or longer. Here's a tip on how you may be able to confirm or dismiss this possible problem by yourself. When the dishwasher complete's a wash cycle turn off the water supply line to the machine ( usually under the sink in the cabinet ) If the unit doesn't fill as it had been, it's probably a faulty water inlet valve. Having said all this, you may want to call in a pro if you aren't completely comfortable doing that. The part to repair it is available at most brick & mortar appliance part centers or you can check out on-line vendors such as repairclinic.com, apwagner.com etc. Supply them with your model AND serial number to be sure you get the correct valve. You can also do a search for part # 1105846 at repairclinic ( that is their part # not B/S/H/ ) you'll see what I'm talikng about. By the way it's about $35. Hope that helps move you forward. Let me know if I can assist you further, or need help on how to change it etc. It's relatively easy with Bosch/Siemens, just turn off the power, the water, access is gained through the kick plate/toe panel below the door. The valve will be on the left and involves only removing 2 screws, the water line in & out and 2 wires which go on either way...they aren't polarity specific. Thanks for coming to "fixya" for your inquiries and please take a second to rate this answer according to my helpfulness. Good luck. Macmarkus :)
