Seeing a Bosch dishwasher E07 error? That E07 code points to a problem with the Zeolite drying system — specifically, water getting where it shouldn’t. The good news is it’s a fixable, roughly $50 DIY repair if you’re comfortable taking the sump apart. Here’s exactly what’s happening and how to fix it.
What the Bosch Dishwasher E07 Error Actually Means
On Bosch dishwashers with Zeolite drying, the Bosch dishwasher E07 error is triggered when water gets into the Zeolite heater container and runs down into the Zeolite fan. The usual cause is a crack or hole forming at the base of the spray arm tube, which lets water travel into the fan area. The fix is to replace the entire spray arm tube assembly.

- Small Flathead Screwdriver: Amazon link (affiliate link)
Step 1: Suction Out the Water
Grab a wet/dry vac and a towel. Create suction on the piece on the side that goes down into the fan to pull out as much standing water as you can before disassembly.
Step 2: Start Taking the Sump Apart
Remove the two Torx screws that hold the sump piece down. There are also two clamps holding it in the middle and two clamps at the top — release those.
Step 3: Remove the Bottom Piece from the Spray Arm Tube
Take the bottom piece off the spray arm tube. This part is difficult to remove — a small screwdriver helps work it loose.
Step 4: Install the New Spray Arm Tube
The old and new spray arm tubes are identical, but the new one comes with a small piece that fits over the base to help prevent the leak from recurring. Install the new tube and that protective piece.
Step 5: Reassemble
Reattach the clips in the middle, put the screws back in, and tighten the other two screws down around the sump. That completes the repair for the E07 Zeolite fan error.

FAQ
Will the E07 come back after this fix? The new spray arm tube includes a protective piece over the base; in my experience I’ve never had one fail again after installing it.
Is the new part different from the old one? The tube itself is identical — the only addition is the small protective piece that fits over the base.
