Dishwasher Rack Not Getting Clean? Bosch Diverter Valve 00751950 – Fix Uneven Water Distribution Fast

A failed diverter valve causes one rack of your Bosch dishwasher to come out dirty while the other rack cleans normally — the clearest sign water is no longer alternating between spray arm circuits. In most Bosch dishwashers, this is caused by a failed diverter valve — the component at the base of the tub that routes wash water between the lower and upper spray arm assemblies on alternating cycles. When it fails, the valve sticks in one position, starving one rack of water pressure entirely while the other receives full flow. ⚡ Common failure point in Bosch SHE, SHP, SHX, SHV, and SHM series dishwashers. Part 00751950 is the genuine OEM replacement that restores proper water alternation and full cleaning performance across all racks immediately.

❓ Is This the Right Part?

This is the correct fix if ALL of the following are true:

• ✔ Dishwasher powers on and completes full wash cycles
• ✔ Water fills and drains normally
• ✔ Spray arms spin freely and are not clogged
• ✔ ONLY problem is one rack (top or bottom) consistently comes out dirty or under-washed

🔧 Common Symptoms

• Top rack dishes come out dirty while bottom rack is clean (or vice versa)
• Food residue left on dishes despite a full wash cycle
• Dishwasher runs but cleaning performance has noticeably declined
• Spray arm on one level has little to no water pressure during the wash

✔ If these symptoms match, this is the most likely failed component in the system.

✔ In most cases, replacing this diverter valve restores full cleaning performance across all racks immediately.

⚙️ Installation

Skill Level: MODERATE — 20–30 minutes. No special tools required. Disconnect power to the dishwasher before servicing. Remove the lower rack and unscrew the lower spray arm to access the sump area. The diverter valve snaps or screws into the sump housing at the base of the tub — remove the old valve, seat the new 00751950 into position, and reassemble. Run a short wash cycle and confirm both spray arms receive water.
