I have a problem with my dishwasher. It's a bosch economicstar. It takes no water in, tap is on, no kinks in lead, it just stopped taking water. It does go through the program normally and does try to pump the water through the arms. It also drains the water perfectly well. I used it for the last week by adding water 3 or 4 times per cycle whenever I heard it sucking water for the cleaning arms. I opened the left side of the machine, where the water inlet/outlet is. I wanted to check whether the waterlock was broke so I disconnected the water inlet hose from the big seethrough reservoir and switched the machine on. After pumping out the remaining water, therewas water coming from the inlet tube. I reconnected the inlet hose and switched it on again after a rset. Now it did work fine. I switched it off, reset the machine and switched it on, no water again. I repeated this, and after disconnecting the inlet hose it worked agsin. Unfortunately only once... Any advice???

There is a water inlet valve (lower front service panel) and solenoid located. Check to make sure that there is no blockage, if the main or other tubing entering or exiting this valve is kinked, the machine will display the check water light. There is also a float switch on the inside of the dishmachine, if it is stuck, the light will go off also. Ensure that water is flowing into the machine, and there are no kinks in any of the hoses. If there arent, look into the float. If it is under warranty, do not attempt to do any of this yourself, call for bosch support first.
Have you insured the unit is connected to a hot water supply line ? The water will not heat until it start's to circulate and activates the "flow switch" in the Bosch dishwashers.
If it is connected to a hot water supply, try running the hot water at your sink taps before turning on the dishwasher. If you still do not have hot water, check your hot water heater or supply.
If it is indeed connected to a cold water supply it will work, just be prepared for very long wash cycles since the Bosch machines will heat the water at a rate of 2F per minute...it could take a long time to reach 155F.
Let me know what you find out and I'll try to assist you in any manner I can going forward.
Typically the "normal" wash cycle should be sufficient and take anywhere from 60min to 120min. under normal conditions. ( Though 120 mins is quite long and should only occur if you had a low hot water supply, i.e. many people showering at the same time ).
The one variable in this is "normal". These machines when connected normal or proper should have a hot water supply and a heating capacity of 2 degrees per minute until reaching 150 degrees.
The other "tip" to consider is the numbers in the display ( depending on the model...not all have led displays ) is not actual time, just estimated time based on the previous cycle.
If you select a normal wash and run the hot water tap at your sink before starting the machine and it still takes in excess of 2.5 - 3hrs. to complete, there's likely a heating problem.
Let me know and we can go from there. The B/S/H/ ( Bosch, Thermador, Gaggenau & Siemens ) dishwasher's have had some issue with the heater relay on the control boards dating back to the early to mid 90's. Just browse through the bosch dishwasher problems and solutions under my profile... http://www.fixya.com/myprofile/solutionsfiltered.aspx?ctgid=131&usrid=3604823
and you'll see what I mean.
Thank you for visiting "fixya", please take a moment and rate the info I provided for you here and also let me know if you require any further assistance.
Welcome to Fixya ! You've come to the right place.
The problem you're experiencing unfortunately is 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 90's.
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, apwagner etc. Do a search for part # 1105846 at repairclinic, 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. Thanks for coming to "fixya" for your inquiries and please take a second to rate this answer according to my helpfulness.
I MIGHT BE GIVING THE OBVIOS ANSWER BUT ALL PIPES MUST BE FREE FROM KINKS,AND THE OUTLET PIPE SHOULD ALSO BE AT A CERTAIN HEIGHT FOR WATER TO DRAIN.
[I PRESUME WATER TAPS ON CONNECTION PIPES ARE SWITCHED TO ON POSITION.
