Who fixes Bosch dishwasher E24 errors in Calgary? Calgary Appliance Repair does — book online or email calgary@appliancerepairneary.com. The E24 error means the dishwasher is not draining. In Calgary, 60–70% of E24 errors are caused by a clogged filter or blocked drain hose — both are DIY-fixable. If cleaning doesn't resolve it, the drain pump likely needs replacement ($200–$320).
The E24 error code on a Bosch dishwasher is one of the most common service codes our Calgary technicians are called to address. It indicates a drainage fault — the dishwasher has attempted to drain and failed to complete the drain cycle within the expected timeframe. The error flashes on the control panel or display, the cycle stops, and water remains at the bottom of the tub. This guide walks through every cause in order from most to least likely, so you can clear the fault yourself or know exactly what a technician will need to do.
What the E24 Error Code Means on a Bosch Dishwasher
Bosch dishwashers monitor the drain cycle using a pressure sensor and a timer. If water hasn't drained to the expected level within a set time window (typically 3–5 minutes), the machine throws E24 and stops the cycle. The error can be caused by:
- Clogged drain filter (most common in Calgary — hard water + food debris)
- Kinked or blocked drain hose
- Clogged or blocked garbage disposal inlet
- Failed drain pump motor
- Drain siphon issue (no high loop on drain hose)
In Calgary, the hard water environment means filters clog faster than in softer-water cities. Bosch's fine mesh filter system (which consists of three components — the coarse filter, the flat fine filter, and the cylindrical micro-filter) captures mineral-bonded food particles that can accumulate to the point of near-total blockage within 4–6 weeks in a hard-water household that skips regular cleaning.
Step 1 — Clean the Bosch Drain Filter (Do This First)
Bosch Filter Cleaning Procedure
- Cancel the current cycle and power off the dishwasher
- Remove the lower rack completely
- Locate the filter assembly in the centre-right of the tub floor — it has a round handle
- Turn the cylindrical top filter counterclockwise and lift it out
- Lift out the flat mesh filter beneath it
- Rinse both filters under hot water, scrubbing with a soft brush
- Soak in 50/50 white vinegar and water for 15 minutes if mineral scale is visible
- Check the filter housing in the tub floor for debris and wipe it clean
- Reinstall both filters, twist the cylindrical filter clockwise to lock
- Power on and run a rinse-only cycle to test drainage
If this clears the E24 error, set a reminder to clean the filter every 2–3 weeks going forward. In Calgary's hard water environment, monthly cleaning is the minimum — more frequently for households that don't pre-rinse dishes.
Step 2 — Check the Drain Hose
If the filter is clean and E24 persists, check the drain hose. The hose runs from the drain pump outlet (under the dishwasher) to the sink drain connection or garbage disposal. In Calgary homes — particularly older Beltline, Kensington, and Mission condos and townhomes where dishwashers are often installed in tight spaces — the drain hose can develop a kink at the rear of the machine or at the point where it connects to the cabinetry.
Pull the dishwasher out slightly (disconnect from power first) and trace the hose. It should have a smooth curve with no kinks. The hose must also have a high loop — routed up to the underside of the counter before dropping down to the drain connection. Without a high loop, water siphons back into the tub after draining, causing continuous E24 errors.
Step 3 — Check the Garbage Disposal
If your kitchen has a garbage disposal and the dishwasher drain hose connects to it, check two things:
- Knockout plug: If the disposal was recently replaced or installed, confirm the knockout plug in the dishwasher inlet port was removed. A forgotten plug completely blocks the drain path.
- Disposal clog: If the disposal is full of food debris or is not draining freely itself, it will back up into the dishwasher drain. Run the disposal for 30 seconds before running the dishwasher.
Step 4 — When the Drain Pump Has Failed
If all the above checks are clear and E24 persists, the drain pump motor has likely failed. The drain pump on a Bosch dishwasher is a brushless motor assembly — when it fails, it either runs but produces no water movement (worn impeller), makes a loud humming but doesn't drain (motor seized), or is completely silent during the drain phase (motor dead).
Bosch drain pump replacement in Calgary costs $200–$320 including parts and labour. It's a 60–90 minute repair and is worth doing on any Bosch dishwasher under 10 years old. Bosch dishwashers are among the most repairable brands — parts are well-stocked in Calgary through authorized Bosch distributors, and the machines are designed for service access.
Calgary Hard Water Note: Bosch recommends running a descaling cycle monthly using a commercial dishwasher cleaner (or citric acid powder). This reduces mineral buildup on the pump impeller, which is a contributing factor in E24 errors on older units. A clean pump impeller drains 30–40% faster than a scaled one.
Resetting the E24 Error After Repair
After clearing the drain blockage or completing the repair, reset the Bosch dishwasher by pressing and holding the Start button for 3–5 seconds until the display clears. On some Bosch models, powering off at the breaker for 60 seconds achieves the same reset. Run a full test cycle to confirm the E24 error does not return.

What does E24 mean on a Bosch dishwasher in Calgary?
E24 on a Bosch dishwasher means the drain cycle failed — the machine attempted to pump water out but couldn't complete the drain within its programmed time limit. In Calgary, the most common cause is a clogged drain filter (hard water + food debris). Clean the filter first — this resolves E24 in about 60% of Calgary cases. If the filter is clean, check the drain hose for kinks, then book a technician to test the drain pump.
How do I reset E24 on my Bosch dishwasher?
After fixing the underlying drain issue, reset the Bosch E24 error by pressing and holding the Start button for 3–5 seconds until the display clears, or by cutting power at the breaker for 60 seconds. Do not simply reset without fixing the cause — the error will return immediately on the next cycle if the drain path is still blocked.
