Bosch Dishwasher E19 — What It Means & How to Fix It
E19 means the circuit that releases the Bosch detergent dispenser has faulted — the solenoid that pops the flap open mid-cycle — so clear any residue, reset once, then expect a technician repair.
What this code means
E19 points at the detergent dispenser's solenoid circuit: the small electromagnet that flips the dispenser flap open at the right moment so detergent drops into the wash. When the board cannot drive or sense that solenoid, E19 appears and detergent may not be released on time. A sticky, residue-clogged flap can mimic it, but the code itself is electrical.
E19 is the dispenser solenoid circuit on Bosch dishwashers. Clearing caked detergent is a fair first move, but if the flap is clean and the code stays, the solenoid or its wiring needs a technician.
Most likely causes
| Cause | How likely | DIY-fixable? |
|---|---|---|
| Dispenser solenoid has failed or its circuit on the board has faulted | Common | No — technician job |
| Detergent residue jamming the dispenser flap | Common | Yes — clean only |
| Loose wire harness between the dispenser and the control board | Occasional | No — technician job |
| Transient glitch after a power event | Less common | Yes — power reset only |
What you can try yourself
- With the machine off, open the detergent dispenser and wipe out caked or damp detergent around the flap and its hinge so it can move freely.
- Flick the flap to check it springs back — a gummed-up flap can trigger the code without any electrical fault.
- Cut power at the breaker for two minutes, restore it, and run a cycle with fresh detergent to see whether the flap releases.
- If E19 persists with a clean, free-moving flap, the solenoid or its wiring is at fault and needs a technician, since the dispenser is wired into the door and board.
When to call a technician
- E19 returns after cleaning the dispenser and resetting power.
- The detergent flap never opens during the cycle, leaving the tablet or powder behind.
- The flap is clean and moves freely but the code stays.
Typical professional repair cost: A detergent dispenser assembly replacement typically runs $130–$280 with labor; a wiring repair can be less.
Frequently asked questions
Why is my Bosch not releasing detergent with an E19 code?
E19 means the solenoid that opens the dispenser flap is not being driven properly, so the flap may stay shut and detergent is not released. Clean any residue around the flap first; if it still will not open, the solenoid or wiring needs replacing.
Can detergent residue cause E19?
A flap gummed up with old detergent can stick and mimic the fault, so cleaning it is a worthwhile first step. But the code itself reports an electrical problem in the solenoid circuit, so if cleaning does not clear it, expect a repair.
Is E19 safe to keep using?
You can run the machine, but without reliable detergent release you will get poor cleaning, and tipping detergent loose into the tub does not dose correctly. Better to have the dispenser repaired.
