Bosch spv2hmx42e dishwasher aquastop triggered — using new detergent

Use only checks that match the exact appliance or system and its official guide.

1. Check 1

   Stop the programme, close the dishwasher's water tap, and disconnect the plug or circuit only when the area is dry and it is safe to do so. Do not reopen the tap just to see whether AquaStop resets.

   Expected result: The appliance is quiet and no new water enters, or water/foam continues to appear or the area is wet.

   Next step: Keep the tap closed and arrange service if water continues, there is water in the base, or power cannot be disconnected safely.

   Why this matters

   Why: Isolation limits further water exposure; continuing water or a wet electrical area is a containment and service issue, not a reset opportunity.

2. Check 2

   Record whether foam was visible inside or around the door, whether the new product was labelled for dishwashers, when the warning appeared, and whether any water was found outside the tub or under the appliance.

   Expected result: There was foam without visible leakage, visible water/leakage, or no reliable observation of foam or water.

   Next step: Use only the observation to guide service information. Do not claim that changing detergent cleared AquaStop and do not run another cycle as a test.

   Why this matters

   Why: Foam is a detergent-use clue, while water in the base or outside the tub is a possible leak-protection clue; the timing alone cannot establish which condition triggered AquaStop.

3. Check 3

   Read the new product label and compare it with Bosch's dishwasher-detergent boundary; remove the product from future use if it is hand-washing liquid, and do not add more chemicals to the machine during the fault.

   Expected result: The product is dishwasher detergent, or it is hand-washing liquid/another unapproved product.

   Next step: Keep the machine isolated until the warning and any water are assessed. After service clearance, use the dose and product specified for the dishwasher; do not use hand-washing liquid.

   Why this matters

   Why: Bosch says dishwasher detergent may be tablet, powder or liquid, but washing-up liquid is too foamy and can damage the appliance. This identifies an unsafe product choice, not necessarily the cause of the AquaStop warning.

4. Check 4

   With water and power isolated, inspect only the visible inlet hose and tap for a kink, crushed section, loose connection, or obvious damage. Do not cut, immerse, open or bypass the AquaStop housing.

   Expected result: The visible hose is kinked/damaged, the tap is closed, or no external issue is visible.

   Next step: If the hose or connection is damaged, keep the tap closed and call service. If there is no visible issue, do not escalate to hose removal after an AquaStop event without Bosch's exact service instructions.

   Why this matters

   Why: The exact-model manual lists hose/tap and inlet/AquaStop screen conditions under the water-inlet indication, but the AquaStop hose contains an electric valve and is not a user-bypass component.

5. Check 5

   Give Bosch or a qualified appliance technician the complete E-Nr/model, the AquaStop warning, detergent label, timing of the foam, any water location, and photos of the hose and base area if safely visible.

   Expected result: The warning clears only after professional assessment, returns after any attempted restart, or cannot be cleared without opening the appliance.

   Next step: Leave the water tap closed and do not bypass protection, remove panels, disconnect wiring or repeatedly run the dishwasher.

   Why this matters

   Why: A recurring or unexplained water-protection warning exceeds a safe detergent-only diagnosis; the manual reserves repairs for trained personnel.
