The short answer
Fault codes on a BlueStar dishwasher usually report a water condition — a fill that did not complete, a drain that did not clear, or water in the base — rather than an electronic failure. Record the code and the point in the cycle it appeared, look it up for your model, and follow it to the water path it names.
What you are seeing
- A code shown on the display with the cycle stopped
- The same code at the same point in every cycle
- A code that clears on a reset and returns after several cycles
- Lights flashing in a repeating pattern instead of a code
- Buttons that respond inconsistently or a display with dead segments
- A near-miss symptom: a machine that will not accept start at all, which belongs on the will-not-start page
- Body: The pattern matters as much as the code: A code shown on the display with the cycle stopped. The same code at the same point in every cycle. A code that clears on a reset and returns after several cycles. Lights flashing in a repeating pattern instead of a code. Buttons that respond inconsistently or a display with dead segments. A near-miss symptom: a machine that will not accept start at all, which belongs on the will-not-start page.
Causes, most likely first
- A fill or drain fault behind the code — Why: most codes are raised because the machine could not reach or clear a water level in the expected time, which on a built-in usually means the supply valve, the trap or the filter.
- Water detected in the base — Why: a leak code stops the machine deliberately, and it is the one code that must never be cleared and ignored.
- A temperature fault raised by restricted circulation — Why: water that is not moving is not heated, so a circulation restriction is often reported as a heating code.
- A loose hardwired connection — Why: a junction-box terminal that has worked loose gives intermittent, changing faults that look like a failing board.
- Moisture at the door wiring loom — Why: the loom flexes through the hinge every time the door opens, and steam plus flexing eventually gives intermittent faults.
- A failed control board or user interface — Why: dead display segments and unresponsive buttons point here, and it is the diagnosis of last resort.
- Body: Ranked by what the codes on this class of machine actually report: First, A fill or drain fault behind the code: most codes are raised because the machine could not reach or clear a water level in the expected time, which on a built-in usually means the supply valve, the trap or the filter. Second, Water detected in the base: a leak code stops the machine deliberately, and it is the one code that must never be cleared and ignored. Third, A temperature fault raised by restricted circulation: water that is not moving is not heated, so a circulation restriction is often reported as a heating code. Fourth, A loose hardwired connection: a junction-box terminal that has worked loose gives intermittent, changing faults that look like a failing board. Fifth, Moisture at the door wiring loom: the loom flexes through the hinge every time the door opens, and steam plus flexing eventually gives intermittent faults. Sixth, A failed control board or user interface: dead display segments and unresponsive buttons point here, and it is the diagnosis of last resort.
What to check, in order
- write down the exact code and the moment in the cycle it appears, because the timing halves the diagnosis.
- look it up for your model rather than for the brand, since code tables differ between generations.
- if it concerns filling, check the supply valve under the sink is fully open; if it concerns draining, clear the trap and the filter.
- reset once at the breaker. Immediate return means a live fault; a return after several cycles usually means a connection.

Second, look it up for your model rather than for the brand, since code tables differ between generations. Third, if it concerns filling, check the supply valve under the sink is fully open; if it concerns draining, clear the trap and the filter. Fourth, reset once at the breaker. Immediate return means a live fault; a return after several cycles usually means a connection.
Checks you can do yourself
- Photograph the code and note the point in the cycle it appeared — Tools: phone — Time estimate: a few minutes
- Find the code in the manual for your model and read what it actually reports — Tools: the model manual — Time estimate: a few minutes
- Check the supply valve under the sink is fully open and the trap and disposal are clear — Tools: torch — Time estimate: a few minutes
- Switch off at the breaker, wash the filter and sump screen, and check the sump chamber for debris — Tools: soft brush, gloves — Time estimate: a few minutes
- Restore power and run the shortest programme, noting whether the code returns and when — Tools: none — Time estimate: an hour or more
- Body: Owner checks stop at the water path and the breaker: Photograph the code and note the point in the cycle it appeared (phone; a few minutes). Find the code in the manual for your model and read what it actually reports (the model manual; a few minutes). Check the supply valve under the sink is fully open and the trap and disposal are clear (torch; a few minutes). Switch off at the breaker, wash the filter and sump screen, and check the sump chamber for debris (soft brush, gloves; a few minutes). Restore power and run the shortest programme, noting whether the code returns and when (none; an hour or more).
Safety first
Safety
Unplug the appliance or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off. Do not open the junction box under the sink to look for a loose connection; it can be live with the machine off at its own controls. Never clear a leak code and carry on using the machine. unplug-before-service
When to stop and call a technician
A code becomes a service call when: It reports a leak or water in the base. It returns immediately after a reset with the water path clear. The display has dead segments or unresponsive buttons. The code changes between cycles, which points at a connection rather than a component.

What this page does not cover
This page is generalized across every dishwasher sold under the BlueStar name: it separates neither the panel-ready cabinets from the stainless-fronted ones and one control generation from another, and it names no individual model. Where a family- or model-specific page exists it is linked here and it outranks this one for that machine; at present no page beneath this one narrows to a single family, so treat the ranking above as the brand-level pattern rather than a reading of your serial plate. For the other faults that turn up on this machine, start from Common BlueStar Dishwasher Problems.
