How to Reset Bosch Washer Error Codes

Bosch washers (the Serie ranges) reset by power discharge like everyone else — Bosch adds no magic button — but Bosch owners often arrive here from the dishwasher side, where the Start-hold reset exists. For Bosch laundry: the power cut is the reset, codes are condition reports that re-measure every cycle, and this page sets out the procedure and the realistic expectations.

The Bosch washer reset procedure

Switch off at the machine, unplug (or isolate at the breaker) for a full 5 minutes. Restore, and run the cycle type that faulted (a Drain+Spin equivalent for drain questions). A code that clears and stays cleared through a full cycle was a transient.

What Bosch codes do after resets

Bosch's E-code system is measurement-driven: drain, fill and motor codes reappear the moment their condition is re-measured. Treat a returning code as a successful diagnosis delivery and use the Bosch code list for its fix path.

Cancelling a programme the Bosch way: Start/Pause, and the door that stays locked

Bosch's washer manuals describe cancelling a programme as a short, specific procedure, and it is the closest thing to a reset button the machines have. In Bosch's current user manuals the sequence is: press the Start/Pause button, then open the door and remove the laundry. The sentence that follows in the manual is the one owners actually meet: if the temperature and the water level are high, the door cannot be opened — for safety reasons, the door stays locked. Bosch does not treat that lock as a malfunction; it is the machine refusing to release a load of near-boiling water or a drum full of water against gravity, and no button combination in a Bosch manual overrides it. Older Bosch manual generations describe the same logic from the other direction, as a change of programme: press Start/Pause, select another programme, press Start/Pause again — and, if the temperature is too high, first select the Rinse programme to cool the load down. Either way, the design principle is consistent across Bosch's documentation: a cancel on a Bosch washer is not an instant stop but a managed handover, in which the machine first brings temperature and water level into the range where opening the door is safe.

Too hot or too full to open: Bosch's cool-down and drain-first branches

Because the door lock is condition-based, Bosch's manuals give the two escape routes explicitly, and together they form the practical 'reset' for a washer stopped mid-programme with a fault showing. If the load is too hot, run the Rinse programme: the manual's own cancel-at-high-temperature sequence is Start/Pause, let the load cool down with Rinse, then Start/Pause again. If the water level is too high, the manual routes you to Spin or a suitable draining programme — in current manuals: if the water level is high, start the Spin programme or set a suitable programme for draining; in the older text, Start/Pause, then Spin or Drain, then Start/Pause. These are not workarounds invented by owners; they are Bosch's printed branches, and they explain behaviour that otherwise looks like defiance — a washer that 'won't cancel' during a hot wash is waiting for the cool-down or drain step Bosch designed, and it will usually complete the cancel promptly once given it. Only when the machine refuses these programmes too — no response to Rinse, Spin or Drain at all — has the situation left procedure territory and become a control or drain fault to diagnose by its code.

The real reset on a Bosch washer: OFF, unplug — and then the code's own remedy

Bosch's own support pages show what 'reset' means when a code is standing, and the E18 page is the model example. E18 is Bosch's no-drainage code (the same fault appears as F18 or d02 on other models — Bosch states they are identical), and Bosch's published procedure does not begin with a button: it begins 'Set program to OFF. Pull out the main plug.' Only after that power-off does Bosch move to remedy — because on a Bosch washer a code is a measurement, and the reset's job is simply to give the machine a clean state from which to measure again. The pattern generalises across Bosch's code pages: E17/F17 (water supply time exceeded) is remedied by opening the tap; the drainage codes by clearing the drainage path; and in each case Bosch closes with the same line — if the error cannot be rectified, contact customer service. So the honest reset sequence for any Bosch washer code is three steps in Bosch's own order: switch the programme to OFF and remove power, apply the remedy Bosch publishes for that specific code, then restore power and run the relevant programme so the machine re-measures. A power-off by itself, with the kinked hose or blocked pump still in place, is a pause — the code will be re-posted at the next drain, correctly.

E18 after the reset: Bosch's published pump and hose procedure

Since E18 is the code owners most often try to reset away, here is the remedy Bosch actually publishes for it, in Bosch's order. Set the programme to OFF and pull out the main plug. Then deal with the water and the pump: open and remove the service flap, let the water drain out through the drainage hose by slowly removing the pump cover (Bosch warns the leaking water may be very hot — risk of scalding — so let a hot load cool first), and clean the interior, the thread on the pump cover and the pump housing; the pump impeller must be able to turn. Re-insert the pump cover and screw it firmly tight, close the service flap, and before trusting it, pour one quart (one litre) of water into the detergent dispenser, check for leaks, and start the DRAIN programme. For the hose side, Bosch's second procedure checks that the drain hose is installed at the siphon without kinks, loosens the hose clip, carefully removes the hose, cleans both it and the siphon spigot, then — holding the hose in a bucket — selects the DRAIN programme to check the pump's delivery, before reconnecting and checking for leaks. Notice what this means for resetting: on Bosch's own instructions, the pump cover, the impeller and the hose are the reset for E18. The code clears when the drain it monitors can actually happen.

Why Bosch washer error codes survive resets

New Bosch owners often read a returning code as a failed reset, but Bosch's design intent is the opposite: the code is the result of a measurement the machine repeats every cycle, so any code whose condition persists is supposed to survive. E17 returns while the tap is closed or supply pressure is low, because the fill is timed again at the next fill. E18 returns while the pump is blocked, because the drum is drained — and timed — again at the next drain. This is also why the same fault wears different names across Bosch's range (E18, F18 and d02 are, per Bosch, the identical no-drainage event): the prefix belongs to the display generation, not to a different fault, and articles or advice that treat them as separate problems are misreading the label. The useful distinction a reset genuinely does draw is between hard and intermittent faults. Clear the code's published remedy, power back on, and run the programme that faulted: a code that never returns was either the remedy working or a one-off measurement glitch; a code that returns at the same programme stage every time is a hard fault in the named system; and a code that returns irregularly — some cycles fine, some not — points at the intermittent class (a partially blocked pump that sometimes clears, a supply that dips under load) that a technician will want described exactly that way.

What Bosch does not publish: no secret reset combination

Close with the same honesty the dishwasher guide uses: nowhere in Bosch's washer manuals or support pages is there a universal error-reset combination — no knob position, no simultaneous-button service trick published for owners. The reset folklore attached to Bosch washers online (spin-button holds, dial-to-a-number sequences) comes from other brands' service procedures and from forums, not from Bosch, and Bosch's own documentation consistently offers three legitimate tools instead: the Start/Pause programme cancel with its hot/full branches, the OFF-and-unplug power discharge that opens Bosch's own code procedures, and the per-code remedy on Bosch's support pages. That is a complete toolkit, and it has a clean stopping rule built in, in Bosch's own words on its code pages: if the error can't be rectified, contact customer service. A code that has had its published remedy applied properly and still returns has given you its answer — it is a component fault now, and the reset era of the problem is over.

After the remedy: prove the reset with the programme that faulted

A Bosch washer reset is only finished when the machine has re-run the stage that produced the code, because that re-measurement is the whole point of the exercise. Bosch builds this proof step into its own procedures — the E18 remedy does not end at the cleaned pump; it ends with water poured in, a leak check, and the DRAIN programme started so the pump's delivery is demonstrated, not assumed. Generalise that discipline to every code: after an E17 remedy, run a fill and watch it complete inside the expected time; after a drainage remedy, stay for the drain and spin rather than discovering a still-blocked pump with a full load at midnight; after a cancel-and-cool-down sequence, run the replacement programme from the beginning instead of resuming mid-state. Two results are possible, and both are valuable. The programme completes cleanly and the code stays gone through the next full wash — the reset, plus remedy, genuinely closed the fault. Or the code re-posts at the same stage, on cue — which converts your service call from 'it shows a code sometimes' into the precise, stage-specific report that gets faults fixed on the first visit. Either way, the watched test programme is what turns a reset from a hope into a result.

Key takeaways

• European Bosch laundry and North American Bosch laundry share the E-code logic but not always the same code chart — confirm with your model's list.
• Keep a note of returning codes with dates; Bosch controls reward pattern-spotting on intermittent faults.

Resetting the Bosch washer

Bosch washer codes clear by cancelling the program (turn the selector to Off, wait a few minutes) followed by a fresh program start; persistent faults need a power cycle of several minutes. A code that returns at the same cycle stage is an active fault.
