Bosch, Read by the Code
Bosch dishwashers are the quiet workhorses of Cobble Hill kitchens, and unlike some premium brands they report faults through a clear E-code family. That is a real advantage, because an E15 and an E24 look similar to a homeowner but point to completely different repairs: E15 is water in the base tray tripping the AquaStop float, while E24 is a drain that will not clear. We read the code to narrow the fault, then confirm the failed part by testing the pump, valve, heater or float directly. It keeps the repair honest, because the code tells us where to look but not which component has actually gone.
We focus on Bosch dishwashers, ovens and cooktops and confirm availability for the relevant parts after diagnosis. Whether it is a Benchmark dishwasher throwing E15 or an 800 Series induction cooktop with a dead zone, the goal is to read the fault, fit the model-specific part and confirm a full working cycle before we finish.

Error and Fault Codes
Bosch dishwashers use an E-code family. The code names the system; we confirm the failed part before replacing it:
| Code | Meaning | What We Do |
|---|---|---|
| E15 | AquaStop: water in the base tray, float tripped | Find and repair the leak, dry and reset the float, confirm no return |
| E24 | Drainage fault, water not pumping out | Clear the filter, hose and air gap, test the pump and check valve |
| E22 | Filter or circulation fault | Clean the filter and sump, confirm the circulation pump moves water |
| E09 | Heating fault, water not warming | Test the flow-through heater and wiring, replace the failed element |
| E01 / E02 | Control-board or heating-relay fault | Test the board and relays, replace the control as tested |
E15 Is a Leak, Not a Mystery
The AquaStop base float trips whenever water reaches the tray. Draining and resetting clears the E15, but unless the small leak from a hose, seal or the sump is found and fixed, the code returns. We always trace the source.
Common Problems We Fix
The most common Bosch call in Cobble Hill is the dishwasher showing E15 after a slow leak has filled the base tray. Close behind are E24 drain faults from a clogged filter or blocked air gap, E09 heating faults that leave dishes wet and cold, poor drying traced to an empty rinse-aid dispenser, and induction cooktop zones that will not detect a pan. On wall ovens we see temperature-sensor faults and door-latch problems. Each has a defined cause we confirm before quoting.
