System architecture
How the electronics are organized
A robust system separates safety-critical valve, pump, motor, temperature, and occupancy control from higher-level UI, storage, and connectivity, with the safety controller retaining final authority over every water, motion, and heating request.
Engineering risks to close
What must be resolved before release
- Maintain water-electric separation and safe shutdown across leakage, temperature, and sensor faults.
- Keep valve, pump, motor, and heater interlocks independent of application-processor or network failures.
- Control condensation, cleaner exposure, connector density, and EMC inside a complex wet appliance.
Validation plan
Evidence expected before production
- Inject occupancy, water-level, flow, temperature, valve, pump, motor, and board-communication faults.
- Test high and low water pressure, blockage, leakage, condensation, cleaner corrosion, and abnormal power loss.
- Perform applicable leakage, grounding, dielectric, surge, EFT, ESD, RF-coexistence, and long-cycle system testing.
Decision-ready evidence packet
What a comparable RFQ should define
This checklist turns the technical story into reviewable inputs and release records. It describes what buyers and manufacturers should agree—not a claim that every listed record applies to every build.
Design baseline
Released schematic or block diagram, interface table, power states, critical constraints, and revision owner.
Manufacturing release
Gerber or ODB++, stack-up, centroid data, assembly drawings, approved DFM dispositions, and panel assumptions.
Material control
Released BOM revision, manufacturer part numbers, AVL or alternate rules, no-substitute lines, MSL handling, and exception approvals.
Validation record
Test method, acceptance criteria, sample or serial identity, measured result fields, and disposition. Example scope: Inject occupancy, water-level, flow, temperature, valve, pump, motor, and board-communication faults.
Production release
First-article status plus the agreed SPI, AOI, X-ray, ICT, FCT, programming, rework, OQA, labeling, and packing records.
Project-specific fields, retention periods, sampling rules, measured limits, and customer approvals are confirmed during RFQ and protected under the applicable confidentiality agreement.
Development and production controls
Manufacturing scope represented here
- Safety-controller and application-board partitioning.
