E8 — Undocumented (Confirm for Your Model)

Bosch's official US refrigeration error-code page documents only three entries: E02 (icemaker/ice-water communication), E03 (dispenser UI), and a generic 'E or D' catch-all. A bare 'E8' is not separately documented. The 'water filter reminder' meaning below could not be confirmed — verify against your model's manual, or treat it per Bosch's generic guidance: power-cycle, and call support if it persists.

How to fix it

  1. Replace the water filter with the correct Bosch cartridge.
  2. Reset the filter indicator from the menu per the owner's manual.
  3. Confirm the household water shutoff is fully open.
  4. Inspect the line behind the unit for kinks.
  5. If water still does not flow, test the inlet valve solenoid for resistance and 120VAC at the terminals during a dispense.

Why it happens

Typical signs: E8 on display · Water dispensing slow or stopped · Ice maker not filling · Filter status light red

  • Water filter past life or clogged Bosch tracks runtime/throughput and triggers E8 at the interval.
  • Water supply valve closed Household shutoff to the fridge is off.
  • Kinked water line Supply tube pinched behind the unit.
  • Failed inlet valve Solenoid valve does not open on command.

Replace your water filter

A clogged or overdue water filter is a common cause of low water and ice flow on Bosch refrigerators — they are meant to be changed about every 6 months. The OEM-style filter that fits most Bosch refrigerators is the BORPLFTR10 ($60-75 OEM, $25-35 compatible).
