Bosch Washing Machine E30 — Check the Model

Bosch US assigns different meanings to E:30/-10 (filling or level measurement), E:30/-20 (excess detergent or water) and E:30/-80 (drainage). The bare E30 in this route does not establish a single diagnosis. This definition comes from the manufacturer’s US guidance. Confirm applicability in the exact UK model manual before using it; regional equipment and code systems can differ.

UK repair-cost context

What might professional repair cost?

These are broad planning ranges, not quotations. The exact model, confirmed fault, location, parts and provider terms can change the price.

Washing-machine engineer assessment and repair

A broad UK planning range for an out-of-warranty engineer visit and repair. The exact figure depends on the model, location, fault, parts and whether a second visit is needed.

Published repair estimate

£70 – £400

This is Checkatrade’s published estimate. Ask whether your quote includes call-out, labour, parts and VAT.

Source: Checkatrade UK appliance repair cost guide · Appliance repair overview table. VAT and call-out inclusions are not specified for this range.

Call-out fee estimate: £60 – £150. A call-out fee is not an hourly labour rate. Ask whether it is included in, credited against or added to the repair quote.

Scope: Use this only after the external checks on the error-code page have not resolved the fault. It is not a price for a named component or a guaranteed quotation.

Method and sources

The displayed numerical ranges come from Checkatrade. Bosch’s call-out and labour charge excludes replacement parts; Beko’s charge depends on eligibility for its parts guarantee. These manufacturer prices provide separate booking context and do not validate the market estimate for every brand or fault. MyJobQuote provides a separate quote-based comparison, not an extra boundary for the displayed range.

Model-level safety check

An error code cannot confirm recall status

Recall and corrective-action programmes apply to specified model or serial identifiers. Use accessible paperwork or a safely reachable rating plate; do not move or dismantle an unsafe appliance to find it.

No model-specific result is attached to this generic code page. That is not confirmation that the appliance is unaffected.

Our checker covers selected tumble-dryer notices only. Check the manufacturer and official UK safety notices for other models. No match is not a safety clearance.

What not to do

  1. Do not remove panels, test wiring, force a locked door or bypass a protective device.
  2. Do not repeatedly reset an unexplained or returning warning, or buy parts solely from this display.

When to call a technician

Contact Bosch support or a qualified appliance technician if the warning remains, the code is not explained in the matching manual, or any internal investigation is required.

Safety warning

Stop if there is leakage, a burning smell, unusual heat or electrical tripping. Keep clear of wet electrical connections. Do not remove panels, test wiring, force a locked door or bypass a protective device.
