Beste Jan ... ondertss gevonden, bedankt !
Via nog ander forum volgende binnengekregen, wat denk je ? The 1min display is actually an error code on your Siemens (Bosch)... ...likely caused by the base (under the tub) being flooded, or at any rate, the water measuring device being clogged. The usual culprit is the water inlet that enters the machine in the sump area. Proceed as follows: 1. Power OFF, Plug OUT.
2. Remove bottom basket completely.
3. Remove filters.
4. With the aid of a torch, examine the sump area. There is a tangential opening at the 6 O'Clock position, on the actual curved body of the sump, at the front of the sump. This leads off left, upwards and backwards. It is a corrugated plastic pipe, and leads to the water level sensors/measuring devices. 5. With the aid of a slim bottle-brush, bent into a gentle curve, GENTLY & CAREFULLY rod the pipe out. You may get a substantial amount of greasy deposits out. This is quite a common fault. 6. Replace filters and bottom basket, and run the machine. The base may also have water in it, causing the drain pump to run indefinately. This can be caused by: 1. a leak from a poor seal, or
2. using multifunction tablets AND using a liquid rinse aid. (Ditch the tablets and try powder and a liquid rinse aid). Some of those tablets are simply far too foamy.
These newer euro washers have so many computer related issues - sometimes it just takes a hard reset - (unplug for 40 minutes) to get the eeprom back to factory start.
From the Bosch Service Manual: Occasionally, dishwashers can run for hours, not finish washing & show a "1" in the display. This means the module (electronic control) has timed out due to an unidentified heating problem -- all heating related parts must be checked until the problem is found. In my own experience as a Bosch service manager, I often found the heater relay and associated solder joints failed, a direct cause of a code "1" error. However, as the service manual states, all heating related parts are suspect until the faulty heating component is verified.
"countdown to 1" is a fairly common problem with the Bosch circuit board. Mine (6yr old Bosch SHU series) has been replaced twice, first time under warranty. The last time, I replaced it myself. It is a plug-in board. The cost of the board was about 120 USD.
